Everyone is feeling the pain.

Justin Timberlake: "My thoughts and prayers are with all those affected by this horrific act in Manchester. We need to do better. We need to LOVE ONE ANOTHER."

A visibly emotional James Corden also delivered a somber monologue shortly after the tragedy, and it's a must-watch. What a sad sad day for people all over the world.

He seems to have weaseled his way back into her good graces.

Mariah Carey grabbed dinner in Malibu with on-again boyfriend Bryan Tanaka last night, and the backup dancer looked quite pleased with himself for winning back the songstress after their brief breakup in April. We get what he sees in her, but what on Earth does she see in him?

The two allegedly called it quits because of Tanaka's outrageous spending habits and his jealousy over her close relationship with ex Nick Cannon, so either she put her beau on a serious budget or she just chose to look past his money grubbing ways. It sounds like Mimi might have just needed a little lovin;, and isn't exactly committing to her boy toy this time around.

"Mariah is not looking to jump into another relationship. She also is not looking to get back together with Nick. They are better off as parents. They are friends and that's it. She has fun with Bryan. She's just enjoying her single life," a source dished to E! News.

Enjoy it while it lasts, dude. And maybe pay off your credit cards before she kicks you to the curb again!

She's finally facing the beef head on!

Katy Perry hopped in the passenger seat for carpool karaoke with James Corden on Monday, and the TV host accomplished what nobody has been able to do thus far, which is to get the pop star to open up about her infamous feud with Taylor Swift.

"Honestly, it’s really like, she started it, and it’s time for her to finish it," she sniped, before revealing that she tried to mend things with a phone call after T-Swizz became upset with her over stealing some of her background dancers.

"I tried to talk to her about it, and she wouldn’t speak to me. I do the right thing any time that it feels like a fumble. It was a full shutdown, and then she writes a song about me, and I’m like, O.K., cool, cool, cool, that’s how you want to deal with it? Karma! But what I want to say is that I’m ready for that B.S. to be done. Now, there is the law of cause and effect. You do something, there’s going to be a reaction, and trust me, Daddy, there’s going to be a reaction," she continued.

"It’s all about karma, right? I think personally that women together, not divided, and none of this petty bullshit, women together will heal the world," she added.

Is it just us, or has KP gotten really annoying in recent months? Further proof of that conclusion is the teaser video she made for her upcoming single "Witness." You have to watch it!

This is all so tragic.

Ariana Grande has suspended her Dangerous Woman world tour in the wake of last night's terror attack at her Manchester concert, TMZ reports. The singer was set to perform in London on Thursday but is said to be "hysterical" over the incident, which claimed the lives of 22 fans and left 119 injured.

"Tonight, our hearts are broken. Words cannot express our sorrow for the victims and families harmed in this senseless attack. We mourn the lives of children and loved ones taken by this cowardly act. We are thankful for the selfless service tonight of Manchester's first responders who rushed towards danger to help save lives. We ask all of you to hold the victims, their families, and all those affected in your hearts and prayers," Grande's manager Scott Braun wrote on Twitter.

ISIS has claimed responsibility for the bloodshed, the Associated Press reports. Authorities have identified the suicide bomber, who died at the scene after detonating a "sophisticated" homemade device in the foyer of the arena.

What is the world coming to? This makes our heart hurt.

Newly-hitched Pippa Middleton and her hubby James Matthews have touched down in paradise for their extravagant honeymoon and X17 has the exclusive pix of the just-married couple as they transferred flights during a layover in LA.

Pippa, 32, wed her financier boyfriend, 41, in a traditional English country wedding near the Middletons' estate. Duchess Kate and Prince William were in attendance, of course, as were their children George and Charlotte. And as their magical day came to a close, they slept just a few hours and then hopped a flight for paradise -- French Polynesia.

We spotted the couple as they made their way through security at Los Angeles International Airport -- Pippa looking tired and James, too. The newlyweds will vacation at The Brando, a private island in the French archipelago on a private island called Tetiaroa. The eco-friendly resort is on the island once owned by Marlon Brando and villas go for anywhere between $3,500 - $16,000/night!

No doubt Mr. Matthews will treat his bride to the most expensive 3-bedroom villa for complete privacy. They can fish, snorkel, SCUBA dive, relax at the pool, play tennis or myriad other activities ... or just enjoy their villa :)

Manchester, England police are treating what happened at Ariana Grande's Monday night concert as a "terrorist incident" until they have reason to believe it's something else. Twenty-two are dead and approximately 50 injured after two explosions were reported at the Manchester Arena as Grande's concert was wrapping up.

Greater Manchester Police released the following statement on Facebook: "Emergency services are currently responding to reports of an explosion at Manchester Arena. There are a number of confirmed fatalities and others injured. Please AVOID the area as first responders work tirelessly at the scene."

The crowd was made up of mostly young people who had come out to see Ariana's first of three scheduled dates in the UK. One concertgoer, Ivo Delgado, told CNN: "It was a really big explosion. Everybody started screaming and running. There were people on the floor ... There was a lot of confusion."

Grande fan Rhianna Burke posted this clip to Twitter; stay tuned for more details ...

Seems a person (like Scott) would have to be pretty heavily medicated to decide to take Bella Thorne with him to Europe. I mean, is the pierced, tattoo'd serial Instagrammer really going to make Kourtney Kardashian jealous? We expect Scott and Bella are Bella's rainbow-haired sister Dani are going to touch down in Nice and head straight to Cannes to flaunt their threesome right in Kourt's face.

Meanwhile, Kourtney's getting cozy with male model Younes Bendjima -- and she has been for quite a while. The two have been prancing around on some billionaire's yacht, riding jet skis and cuddling on deck. Is Scott gonna drag his 19-year-old Fruit Loop to some chic party on the Croisette and think that Kourt's going to do anything but laugh? Really, Scott ... you could do better.

Well this is embarassing https://t.co/XaPL1AbCm5 pic.twitter.com/mumhuQHDFz

They seem like they have a loving relationship... not!

Melania Trump knows cameras are always capturing her President husband's every move, but she didn't seem to care when she swatted away his attempt to hold her hand during their arrival in Israel. In the video, you can see the POTUS reach for her manicured mitt before she pulls it out of reach. Ouch!

This isn't the first time the real estate mogul's spouse has shown her displeasure in public. Memes of her glum facial expression at the Inauguration went everywhere, and she made no excuses for them.

"Melania does not keep hidden from everyone around her how miserable she is. They have separate bedrooms. They never spend the night together — ever," a source previously dished to Us Weekly.

Another person who probably wishes they had never met The Orange One? Billy Bush.

The disgraced TV host finally broke his silence on that "p**sygate" Access Hollywood tape, and he acknowledged his poor choice to take part in the vulgar discussion.

"Looking back on what was said on that bus, I wish I had changed the topic…[Trump] liked TV and competition. I could’ve said, ‘Can you believe the ratings on whatever?’ I didn’t have the strength of character to do it," he told The Hollywood Reporter.

As for how his family processed the scandal?

"There was a powerful moment — my now 16-year-old daughter called me ... and she was in tears. She was really upset, and I said, 'Mary, it's, it's going to be OK. You know, don't worry,' And she said, 'No. Why were you laughing at the things that he was saying on that bus? Why were you playing along with it, Dad? It wasn't funny,'" he explained to GMA's Robin Roberts.

Our commander-in-chief seems to have more than a few people that aren't too fond of him anymore!
