Yay! Are Ariana Grande and Big Sean really back together?

Well if her single, "Break Up With You Girlfriend, I'm Bored" is any evidence, Ms. Grande's had her eye on Sean for a hot minute ...

The former couple were spotted leaving a San Fernando Valley recording studio together late last week, Ariana hiding her face with her cute puppy. Sean was behind the wheel of his black Mercedes sedan and it really reminded us of old times ... like they were totally back together!

Adding to it, Sean just broke up with long-time girlfriend Jhene Aiko in December, so he's a free man.

Meanwhile, Ariana's got a lot on her mind and it's mostly about healing from a tough few years. She posted a heartfelt message to her fans on Friday about getting through the Manchester tragedy, Mac Miller's death and through her breakup with Pete Davidson: "mmmmk …. about to embark on my third tour and am for sure deep as f–k in my feelings. and getting my period so…. this is probably gonna be too much. But i just want to say how grateful i am for my life, for the people in it, for the ups and challenges, for the laughter and the pain, for this music and for the lifelong friendships i’ve made thru making it (that includes my friendship with y’all). Maaaaaaaan… i cant really fathom all that has happened over the past few years. I don’t even really know where i’m going with this post but i’m just grateful to be here still. and excited to see you. i’m prolly gonna cry a lot."

We hope Ari has a good time on the road and keeps her head up. And maybe she'll get a little (or a lot of) support from Big Sean!

Khloe's walking back her previous statement that Jordyn Woods is responsible for the breakup of her family ...

True Thompson's mommy took to Twitter Saturday to apologize and to retract her previous Tweets blaming sis Kylie Jenner's BFF for what happened between the model and Tristan Thompson and she's now blaming it on Tristan.

She was an open book this morning when she posted: "This has been an awful week & I know everyone is sick of hearing about it all (as am I). I’m a rollercoaster of emotions & have said things I shouldn’t have. Honestly, Tristan cheating on me & humiliating me, wasn’t such a shock as the first time."

She went on ... "What’s been harder & more painful is being hurt by someone so close to me. Someone whom I love & treat like a little sister. But Jordyn is not to be blamed for the breakup of my family. This was Tristan’s fault."

Sounds like there's been a lot of talking going on behind the scenes. Perhaps since Jordyn's Red Table Talk with Jada Pinkett Smith hit the Internet, Khloe's felt a little guilty about publicly punishing Woods. She went on to write, "I have to move on with my life & count my blessings, my family, my health, & my beautiful baby True."

Here, here! Now let's just hope she doesn't get roped back in by Tristan ... she DID finally unfollow him on Instagram. Whoa!

What's THIS?! We spotted Juul vape in Selena Gomez's hand as she entered a Valley studio on Friday. Isn't she supposed to be careful with her health, given her Lupus and kidney transplant?!

Well it certainly seems like she's Juul'ing and we've never known her to be a smoker so we can only imagine it's for pleasure ... OR to intake CBD oil for health-related pain? Or for anxiety?

Perhaps that's an aid for mental health issues she's suffered recently. Some research claims the marijuana extract helps with anxiety and depression, so it's a natural way to treat those problems. Is that what this is???

Justin Bieber knows what he needs to do to stay faithful to wife Hailey Baldwin! The singer is reportedly FORCING himself to stay away from ex Selena Gomez to ensure his fidelity to his partner.

Perhaps Justin doesn't trust himself around Selena -- after all, lots of people are weak around their first loves -- but her health issues have made it tough. After complications from her kidney transplant which then led to a nervous breakdown, Justin's tendency would be to rush to her side. The desire to go to her, to help her, to nurse her was strong -- hence Justin's numerous public breakdowns right after he and Hailey tied the knot. When he got the news Selena was hospitalized for mental issues, it cause him his own mental issues that he's now been battling.

Justin's been holed up with pal/mentor Pastor Carl Lentz, seeing spiritual guidance and perhaps medical guidance as well. We spotted the singer at the Amen Clinic in LA numerous times before he left town for a self-imposed exile. Reports claim his been dealing with depression and that it's not related to his marriage, but other issues (aka Selena). Seems he's having a hard time letting go and staying away but he knows it's what he needs to do to keep his marriage strong. Question is ... can he do it?

Poor girl! Amanda Bynes has had a tough time of it ...

The actress entered a mental health facility in 2014 after a very public breakdown involving bizarre social media posts that drew attention to her issues. When she completed treatment she was released to her parents' care and her mother was Bynes' legal conservator over Amanda's "person."

But it seems Bynes' drug use may have caught up with her again. She has admitted smoking pot in her early teens, which progressed to using ecstasy and molly, and to abusing Adderall. She ended up dropping out of the movie Hall Pass because she was too "scatterbrained" to finish filming but it was the Emma Stone film Easy A that made Bynes stop acting all together. She explained: "I literally couldn’t stand my appearance in that movie and I didn’t like my performance. I was absolutely convinced I needed to stop acting after seeing it,” Bynes explained. “I was high on marijuana when I saw that but for some reason, it really started to affect me. I don’t know if it was a drug-induced psychosis or what, but it affected my brain in a different way than it affects other people. It absolutely changed my perception of things."

Is that bad brain chemistry coming back to haunt her? Or perhaps she's using again ... either way, Bynes is clearly struggling and we wish her the best in getting the treatment she needs!

Khloe Kardashian isn't gonna let some jezebel slow her down ... she was back to work today taping KUWTK at their Calabasas studio. The newly-cropped bottle blonde carried a hot pink Hermes back and wore -- funny enough -- a Playboy hoodie with leggings.

Khloe must be feeling a bit sicker after listening to former friend Jordyn Woods' Red Table Talk interview by another family friend Jada Pinkett-Smith. The self-serving appearance saw Jordy saying she'd even take a lie detector test to "prove" she didn't sleep with Tristan but only that he gave her a kiss on the lips as she left his house the morning after a party he hosted. Uh, yeah ...

Woods also said there have been death threats against her family -- which IS crazy. She says that's the reason she wanted to speak out and set the record straight.

Well Khloe called the whole thing "lies" and blames Jordyn for breaking up her family. Now frankly, Khloe's overdoing it a little -- Tristan is a BIG TIME dirty dog and if he hadn't been with Jordyn, it would have been (and probably had already been) with someone else anyway. Poor girl just can't catch a break, though!

Are they or aren't they?!

We caught Selena Gomez heading into the recording studio in Beverly Hills yesterday, and we tried to ask her about the rumors she's secretly dating Zac Efron, but she didn't want to give us an answer. Hey, she didn't say no!

Apparently, SG and the High School Musical star have been getting close in recent months, but pals fear they'd be a bad match, as they both have personal issues that they struggle with.

"There’s definitely an attraction. They've been hanging out and talking, but the concern lies in their highly sensitive personalities. A lot of people think their chemistry is a recipe for disaster. Both of them tend to go off the rails when they’re not living a fully focused, hyper-regimented lifestyle with a team of helpers keeping them on track," a source dished to Radar.

The "Come & Get" songstress has been to rehab multiple times to deal with anxiety and depression, while the A-list actor has done a couple stints of his own for drug abuse.

We know he's dating Lily Collins, but we think Selena and Noah Centineo would be a cute couple!

They're doing things the modern way!

Prince Harry and Meghan Markle plan to raise their child in a gender fluid environment, so don't count on seeing any pink or blue outfits any time soon!

"Meghan has been talking to some of her friends about the birth and how she and Harry plan to raise their baby. Her exact word was fluid," a source dished to Vanity Fair.

"She said they plan to raise their child with a fluid approach to gender and they won’t be imposing any stereotypes," the source added.

Even though they're rumored to enemies, Kate Middleton plans on throwing her sister-in-law a baby shower of sorts before she pops in late April.

"There is still going to be some sort of private baby-centric event for Meghan’s U.K. people, and Kate will host. Her glam people and other relatives will be there. Not sure if it’s a total baby ‘shower,’ but you could probably call it that," a source dished to Us Weekly.

As for the littlest royal's gender? People were speculating it was a girl after the pink-themed baby shower, but apparently the Duchess of Sussex was telling pals at the bash that she was actually expecting a boy.

We're dying to know what name they will chose for their little heir!
