Stephen Colbert’s first guest on the “Late Show”… Dwayne Johnson signed on fro “Baywatch” movie… Zayn Malik and Perrie Edwards drama… Ben Affleck, Tom Brady and nanny update and Howard Stern reveals details about Jennifer Aniston and Justin Theroux’s wedding

Stephen Colbert finally takes over CBS’ “Late Show” on September 8, and now we know his first guest will be George Clooney and his first musical guest, Kendrick Lamar, who just so happened to be Stephen’s last musical guest on “The Colbert Report.” It’s like he’s picking up where he left off!

If you hadn’t heard yet, Dwayne Johnson has signed on to do a “Baywatch” movie, and yesterday he tweeted, “BIG NEWS: Welcoming my dude @ZacEfron to #BAYWATCH. Our movie will be big, fun and RATED R.. Like me when I drink.” According to The Hollywood Reporter, the “Baywatch” movie will follow a “by-the-book and very serious lifeguard (The Rock!) who is forced to team up with a young rule-flouting hothead (Zac!).” Reportedly, their characters must join together to go up against an oil tycoon who is threatening to destroy their beach. So basically, they’re beefcake environmentalists! Look for it in theaters in 2017.

Zayn Malik ended his engagement in the worst way possible. During a party to celebrate Little Mix’s single “Black Magic” going to number one in the UK, Zayn texted Perrie Edwards to tell her they were through. Reportedly, she hasn’t heard a word from him since. Now Little Mix is traveling the US promoting “Black Magic” and after a stop at a radio station in Arizona, the group came out to a crowd of fans and one of them was holding up a sign that said, “Zayn is irrelevant, anyway!” Perrie reportedly said, “Don’t show that, but it’s true.” But then her bandmate Jade decided that was a poster worth keeping and carried it to their car while Perrie followed smiling and waving. Of course, Zayn and One Direction fans don’t like that one bit! As one tweeted, “WOW Little mix.. Zayn spent like 3 years promoting you guys and now this is what you do?”

Page Six has the photo and story — Ben Affleck’s nanny sitting on a private jet rocking Tom Brady’s four Super Bowl rings. How did this happen? According to their source — and I’m guessing it’s the same person who supplied them with the picture and I’m guessing that’s the nanny herself — Christine Ouzounian had been in the Bahamas with Ben and his wife Jennifer Garner. Ben asked Christine to join him on a flight back to LA while Jen stayed behind with the three kids. The source says that along the way, Ben convinced her to go to Vegas with him for a poker tournament and they stopped and picked up his good buddy, Tom Brady, to tag along. The source says while he was in Vegas, Ben kept Christine hidden the entire time. But when they got back to LA, Jennifer found out about the trip, flipped out, and THAT’S when she fired the nanny. Three days after that photo of Christine was snapped on the private jet, the couple announced they were getting a divorce. And People is reporting that Ben put Christine up in the Hotel Bel-Air from at least July 29 to August 4 to avoid the spotlight when the scandal broke. A source said her room alone would run $1500 a night, which would put her six-night stay at over $10K — just for the accommodations alone. And a source said Christine took advantage of the situation — treating her friends to food and drinks and visiting the hotel spa at least twice…and all on Ben’s tab.

Howard Stern says he was one of the few people told ahead of time that Jennifer Aniston and Justin Theroux were getting married because Justin wanted him to give a speech at their wedding. He revealed some of the details of the surprise wedding, including the fact that Jimmy Kimmel officiated and Sia performed. He was NOT happy that guests were asked to turn over their cell phones and spent the first ten minutes of his speech complaining about that and the seating. He said, “They had these little tiny, like, little pillow poufs. I’m 6-foot-(blanking)-5!” and “I got up and I said … ‘Why can’t I have my (blanking) cellphone?’ In other words, I don’t want to take a picture of you two! I really don’t. I want my cellphone so after I make this speech I can call my car and get the (blank) outta here!”
