Ariana's getting a little emotional, being on the road all alone after all she's been through recently ... and she took to Instagram to post about her loneliness ... and about "letting go."

She wrote: "Sometimes, the reason for letting someone go is because they can’t help but hurt you during this phase of their life. When you love someone deeply, you learn what demons live within them and you realize they are hurting you because they are hurting somewhere within themselves. They are fighting a battle within and may not even know it, so they take it out on you and fight you. Decide to let them go, but not because you’re being petty and resentful. You let them go because you really believe that the both of you can find the healing you truly need without being together and hurting each other in the process. Letting someone go doesn’t mean you stop loving and caring about anyone. Letting go means you’re choosing freedom over the illusion of loyalty.”

The singer is preforming in New York right now, on her Sweetener tour and we kinda think she's missing her hometown boy Pete Davidson. Her ex has, of course, since hooked up with the much-older Kate Becksinsale and is currently in LA after having just met HER PARENTS! In fact, we spotted him last night leaving a club in a High Times hooding, smoking a cig and drinking a Red Bull. He looked a little worse for wear ...

FINALLY! Mr. and Mrs. Justin Bieber are ready to put down roots in their new $8.5M Beverly Hills mansion and we've got the EXCLUSIVE pix of their new estate and what they're doing to amp up their privacy.

For the time being, Justin and Hailey are spending time at his Montage Laguna Beach residence -- they split their time between there and the Beverly Hills residence but have opted for the beach locale lately because it's closer to where Justin's receiving treatment for depression -- but more on that later ...

The couple plunked down just under $10M for the 6,100 square foot remodeled transitional-style home. The home was built in the 1930s and was recently remodeled by designer Charles Infante. The home boasts 5 bedrooms, 7 bathrooms, a library and a home theater. The state of the art kitchen includes a wet bar and wine cellar for entertaining guests.

We spotted landscapers delivering trees to add privacy to the property before Justin and Hailey officially move in, which we imagine will be soon. The home's on a quiet cul-de-sac near neighbors Victoria and David Beckham. Maybe they'll have backyard barbecues together! Check out our gallery of their new digs below and video of the landscape work they were having done this morning ...

Joe Termini for Roxy

Hailey Baldwin is NOT a fan of social media -- to the point where she even deletes Instagram sometimes, she admits.

The model would seem to have nothing to worry about, with a Roxy-worth bod as she shows off in the swimwear line's new campaign ... but EVERYONE'S got haters on the 'Gram, apparently. And when you're Mrs. Bieber, there are plenty of jealous people to post negative comments that would send some ladies off the deep end -- but not Hailey.

Hails tells Cosmo: "I’ve found that I got to a place where I don’t read the comments." She's realized it's just not worth it: "You still care to a certain extent. You really have to train your brain to be like, ‘Okay, why do I even care? I don’t know these people, they don’t know me, they’re not a part of my life or my relationship.’ People can just be mean, and I feel like if you don’t want it to get to you, then don’t read it and allow it to affect your soul."

Mrs. Bieber also tells the mag she sometimes takes a complete break from social media: "Sometimes I delete Instagram for a couple days at a time, which is really nice. I’ve done that when I’ve felt like I really couldn’t handle what people were saying or it was like what I was looking at was unavoidable."

Hailey's making the rounds promoting her new line with Roxy, along with her BFF professional surfer Kelia Moniz. The lovely ladies posed for Roxy and it was totally organic -- they're best buds AND Kelia's hubby Joe Termini shot the campaign. Moniz tells Cosmo she's amazed at her friend's composure, being in the spotlight as she is: "Watching the way this girl handles her life under the microscope of literally the entire universe...She holds the standard of who she is as an individual so high. She’s the same consistent human being, always. And she goes through all the craziness of her life so positively and strongly and doesn’t let all the outside comments and all the things of life hinder her spirit, and it’s really really inspiring to see."

We think Justin's inspired by it as well -- in fact, we suspect part of the reason he married Hailey was for the stability she brings to his life. As he battles depression and anxiety, Baldwin is always there for him and is a calming influence. Just see how relaxed and ADORABLE the pair was earlier this week at the beach in our EXCLUSIVE PHOTO GALLERY!

#ad Loving how my tummy looks right now you guys! I brought @flattummyco’s meal replacement shakes into my routine about 2 weeks ago, and the progress is undeniable✨P.S the shakes are 20% off today and you can get Flat Tummy Tea at a really good deal too. Go check it out!

A post shared by Khloé (@khloekardashian) on Mar 20, 2019 at 4:00pm PDT

We're sure this product had everything to do with her ripped physique... not!

Khloe Kardashian showed off her unbelievable body in nothing but jeans and a bra while promoting Flat Tummy Tea on Instagram yesterday, and we can't believe how much weight she's lost since giving birth!

"#ad Loving how my tummy looks right now you guys! I brought @flattummyco’s meal replacement shakes into my routine about 2 weeks ago, and the progress is undeniable✨P.S the shakes are 20% off today and you can get Flat Tummy Tea at a really good deal too. Go check it out!" she captioned the post.

Some fans aren't too happy she's plugging brands that might be dangerous to your health, and one of those people is The Good Place actress Jameela Jamil.

“If you’re too irresponsible to: a) own up to the fact that you have a personal trainer, nutritionist, probable chef, and a surgeon to achieve your aesthetic, rather than this laxative product… And b) tell them the side effects of this NON-FDA approved product, that most doctors are saying aren’t healthy. Side effects such as: Possible Flat Tummy Tea side effects are cramping, stomach pains, diarrhea and dehydration… Then I guess I have to," she commented on the social media site.

"It’s incredibly awful that this industry bullied you until you became this fixated on your appearance. That’s the media’s fault. But now please don’t put that back into the world, and hurt other girls, the way you have been hurt. You’re a smart woman. Be smarter than this," she added.

We want to know what she's really doing to get these rock hard abs!

Random!

Lady Gaga ended her engagement to fiance Christian Carino during Oscar season, but she might already have a new man... and no, it's not Bradley Cooper!

The singer is reportedly "hanging out" with actor Jeremy Renner, although a source tells Us Weekly they "don't believe it’s romantic at this point." Key word - yet!

The Hurt Locker star, 48, shares a six-year-old daughter Ava with ex Sonni Pacheco. He largely stays off the Hollywood dating scene, so this would be his most high profile romance to date.

Before getting engaged to Carino, Mother Monster was previously engaged to TV star Taylor Kinney.

The Star is Born beauty clearly doesn't have a type!

This was quite the soiree!

Kathy Hilton threw herself a 60th birthday party at Mr. Chows in Beverly Hills last night, and her famous pals came out in force!

Paris Jackson showed up with boyfriend Gabriel Glenn, despite her reported suicide attempt less than a week ago. Real Housewives of Beverly Hills star Kyle Richards was also in attendance, after mending her years long rift with her sisters. Kris Jenner rolled solo and looked like a total boss in a black pantsuit, while Nicky Hilton left her kids at home with a sitter to join her mom.

The occasion was heavily documented on social media, and included toasts for the b-day grandma from all the famous faces sat around the table.

"I love you and I hope you'll always be here because I want to be with you. I love you and you mean so much as a friend," Paris Jackson said as she fought back tears.

"I love u so much, you're my best friend, you are everything, I wouldn't be the person I am today if it wasn't for you. You've the biggest heart in the world. You're so funny, you're so generous, with your time, with your laughs. I literally I don't know what I'd do without you. You're so hot, you've the best genes. All of your friends are so gorgeous, everyone loves you so much, you have this ray of light that shines through you," daughter Paris Hilton gushed.

You know you're popular when you have the Kardashian matriarch as part of your squad!

The damage has been done.

Kylie Jenner is reportedly "over" trying to mend her friendship with former BFF Jordyn Woods in the wake of the Tristan Thompson cheating scandal, TMZ reports.

The LipKit queen hasn't had much contact with her once-close pal ever since Woods sat down on the Red Table Talk with Jada Pinkett Smith and denied hooking up with Khloe's baby daddy, but her stuff is still in Kylie's guest house and she's yet to fully move out.

Sources tell the site that the reality star doesn't want any animosity or drama between them, but simply can't forgive Woods for betraying her sister and family.

"She has been socializing more and trying to find a bigger circle of friends that she can be close with. After the Jordyn drama, she realized that relying on just one friend is not the best idea," a source told People about the Keeping Up with the Kardashians star.

Now she just has to hope that Jordyn doesn't spill her deepest, darkest secrets!

Holy rollin' in style!

Justin Bieber and Hailey Baldwin pulled up to church last night in their new black $250K Lamborghini URUS, and the ride must be fun to drive, because we haven't seen them smiling this wide in a long time!

Another big purchase they made recently? An $8.5 million Beverly Hills mansion! The couple have been house hunting in LA for some time now, and they've finally decided to put down roots at the 6,100 square-foot five bedroom, five bathroom Colonial pad.

Mr. and Mrs. JB are certainly making a lot of big decisions, given that they're still working through issues in their relationship. Let's hope it lasts, or else this divorce is just getting more complicated by the day!

The singer's battle with depression and anxiety has caused them to postpone their wedding ceremony, and now some are wondering if they will ever actually make it down the aisle.

A source tells X17:

"Justin is really struggling. Hailey has been doing her best to be there for him, but it really is a personal and private journey. He can't understand why he seemingly has everything he ever wanted but is still so unhappy. He has moments when he feels ready to return to music and be in the spotlight, and then he has moments where he wants to just disappear and live a quiet normal life in Canada. It scares Hailey because his moods shift so rapidly, she never knows if one day he's going to wake up and not want to be married anymore."

Hopefully their worship session brought them some clarity and peace!
