Happy birthday, Cait! Kylie Jenner threw a beautiful birthday party for her dad Caitlyn at Nobu Malibu, on Tuesday night. Caitlyn's partner Sophia Hutchins was there; Kylie's sis Kendall was there, half-sisters Kim and Kourtney Kardashian, Caitlyn's son Brody and his pregnant girlfriend, but NOT Brandon Jenner and NOT Khloe Kardashian -- the two of Caitlyn's kids who have beef with the former Olympian.

Kylie posted on her Instagram Story: "Thank you, Nobu, for setting this up. I set up the cutest little dinner for my dad!"

Kim posted a video of the group singing "Happy Birthday" to the 70-year-old. 70!!! She looks 50! Of course there has been a little plastic surgery ... Caitlyn says in the video, "I wish we could all get together more often." Awww!

Meanwhile, her son Brody was in Australia and daughter Khloe was busy at a Good American denim photo shoot all day -- thought we're not sure why that would preclude her from attending a dinner party. Anyway, HBD, Caitlyn!

Ben Affleck is back on daddy duty following some hard partying last weekend at a Halloween party where he was seen stumbling to get in a car with his new girlfriend Katie Cherry. The actor dropped off his two younger kids at school, on Tuesday, after telling paparazzi the day before that he wasn't going to let one slip-up get in his way of his sobriety. Good for him!

But a new report claims friends are worried. The Unicef Halloween party where Ben indulged, had an open bar and Affleck was all over it, drinking "clear liquid" -- either tequila or vodka, according to an eyewitness. Us Weekly reports that those close to Ben are worried: "The people who care about Ben know where this is headed. If he doesn’t get help, he won’t be able to stop," the mag attributes to a source.

After the party, the pair were seen at a casino, according to the report -- gambling being another of Ben's addictions that, sources tell us, he has never gotten rid of. Affleck's a regular at weekly poker games with pals like Leonardo DiCaprio and Tobey Maguire where there are plenty of temptations, including women.

But Ben swears this won't "derail" him. We hope he's right!

Let's get ready to ruuuuummmmmbbbbblllllle! As Logan Paul and KSI prepare to face off again in the ring on Nov. 9, their fellow YouTubers are weighing in. FaZe Banks tells us: "Honestly, KSI is one of my boys since day one. KSI is my boy for life! I will say this, what I do know is, Logan's in good shape."

Meanwhile, Logan's bro Jake looked a little shocked when was asked him about his brother's rumored head injury. Watch!

Camila Cabello just says NO! We asked Ms. Cabello about rumors she and boyfriend Shawn Mendes have broken up and you need to just watch and listen, folks. After this, you won't question!

God's plan! James Corden got some deep thoughts outta Kanye West in this new installment of Airpool Karaoke -- a spin-off of his popular Carpool Karaoke.

What does Ye have to say about the Devil trying to take him about and being saved by God: "God’s always had a plan for me, and He always wanted to use me, but I think He wanted me to suffer more and wanted people to see my suffering and see my pain and put stigmas on me and have me go through all the experiences, the human experiences. So, now when I talk about how Jesus saved me, more people can relate to that experience. If it was just, ‘Oh, we grew up with this guy’s music and now he’s a superstar,’ it’s less compelling than, ‘Oh, this guy had a mental breakdown, this guy was in debt, this guy’s been through — not been through — this guy’s had a beautiful five years of marriage.’" Truth!

Here's some other stuff that happens ... Kanye beat boxes; he tells James the ONE LINE that he knows made him famous; and there's LOTS of gospel. Watch!

This seems a little calculated ... Ben Affleck turned up at ex-wife Jennifer Garner's house yesterday with a huge smile on his face, not looking hungover AT ALL, after supposedly getting drunk the night before at a Unicef Halloween party.

TMZ had video -- supposedly of Ben, but maybe not? -- literally falling-down drunk after the benefit event, grabbing onto an SUV as he almost tumbled to the ground and then getting into a car with a cute girl. So of course we all assumed he'd fallen off the wagon. Today Radar is reporting that Ben was downing shots of "clear liquid" -- either "vodka or tequila" at the party. But yesterday afternoon, we spotted Ben looking totally fine, hanging out with kids Seraphina and Samuel, clutching an iced coffee.

Maybe Jen invited him over, told him to put on a smile, and look at the cameras, in order to dispel the reports he'd lost his year-long sobriety streak?

Kylie Jenner's chauffeur was a buzzkill Saturday night as the makeup maven and her BFF rolled up to Demi Lovato's Halloween bash at Hyde nightclub and got in a fender bender in the parking lot! In front of the paparazzi, Ky's driver reversed into another car and when he pulled forward, paps, party-goers and fans could hear the horrible scrape of the bumpers rubbing against each other. Instead of sucking it up and heading inside, Kylie told her driver to continue on through the parking lot and head home! Too bad her awesome Madonna costume didn't get more play!

Meanwhile, her BFF Stassie Karanikolaou -- dressed as Britney Spears to Kylie's Madonna, circa MTV VMA Awards 2003 -- watched in shock as Kylie's Range Rover reversed into the car behind it ...



Check out Kylie and Stassie's AWESOME partner costume that went basically unseen, except for the bazillion views this video got on social media!

👰🎩 It seems this iconic video has inspired @KylieJenner today 😏 #LikeAVirgin #VMA pic.twitter.com/2ptY4c21gm

Beach volleyball never looked so good! Victoria's Secret model Alessandra Ambrosio and her equally beautiful friends took the beach over the weekend for some hot-girl summer (even though it's fall) beach volleyball and we were THERE for it! Literally ...

We snapped these exclusive shots of Ally as she served, spiked and otherwise KILLED it on the sand wearing a barely-there gold bathing suit topped off with a red tee. Clearly she's flexible and is able to dive (and kick!) the ball -- probably because of her dedication to the practice of yoga. In fact, we caught her headed to do her downward dog just the day after!
