When late-night show hosts collide! James Corden (CBS) visits Jimmy Kimmel (ABC) and wackiness ensues. Well, actually it's a pretty formulaic visit -- we're kinda surprised. Nothing too crazy went down -- Corden cracked jokes; Kimmel asked prescribed, pre-practiced questions (randomly asking about Corden having an "accent coach" to lead into some jokes for James); and calculated hilarity followed.

Jimmy asks about Corden's Carpool Karaoke with Kanye West and how it all went down -- check out James' response ...

Ben Affleck and Jennifer Garner took the kids to the local YMCA Christmas Tree yard after church on Sunday. Despite being divorced and living apart, the former couple spent the entire Thanksgiving weekend together as a family. That said, the two didn't look so happy together after church yesterday, as they were doing the most exciting thing ever for their kids -- buying their Christmas tree!

They really made it a point to spend the entire Thanksgiving break together with the kids -- going up to Santa Barbara for a night with the entire family, church on Sunday with Ben's mom and the kids, and then straight off to buy a Christmas tree!

From Jamie Foxx and his teenage daughter, to EJ Johnson and his crop top, to new literary darling Flea, to Reggie Bush and his Kim K-look alike wife, this was the motley crew at the Lakers game Sunday night!

The home team was trumped by the Dallas Mavericks, unfortunately, by the die-hard fans were still there to support. Check 'em out! ...

Just 'cause she's a multi-millionaire triple threat and just because her fiance is a Hall of Fame baseballer doesn't mean this mega couple skips out on Black Friday deals!

Jennifer Lopez and Alex Rodriguez don matching monochromatic ensembles for a Black Friday shopping spree in Beverly Hills. J Lo looks super chic in her black turtleneck and leather joggers, while keeping warm in her ankle-length wool jacket. A-Rod mirrored her look by sporting black jeans and knee-length wool coat while getting some amazing deals at Intermix as fans watched!

Justin Bieber and Hailey Baldwin may have chosed a lovely Christmas Tree at Mr. Jingles' lot, but they damn well aren't gonna strap that sucker to the roof of their $200K Lamborghini Urus! It may appear the couple left empty-handed, but we're pretty sure they got a 14-footer delivered to the house!

So this is weird ... Ben Affleck and Jennifer Garner spent Thanksgiving together with the kids, contrary to reports that Ben was away partying in the Bahamas with friends. Mr. Affleck was safe and sound with Jen and their three children and his mom, enjoying a turkey dinner on Thursday and they took this together-time a step farther with a road trip to Santa Barbara!

We spotted the pair in the street in front of Ben's Pacific Palisades home -- just a few blocks away from Jen's house -- getting into a pretty heated argument before Jen jumped behind the wheel to chauffeur the former couple to Santa Barbara. And there were NO KIDS with them ... just these two alone, for almost two hours, chatting and maybe fighting, and drinking coffee.

About an hour in, they stopped at a Starbucks drive-thru where their moods seemed to have calmed. They must have met up with the kids at the chic Miramar resort because when Jen was getting in the car she was carrying a game of Boggle and one of her daughter's books (both Seraphina and Violet are voracious readers). The nanny must have driven up separately with the kids so Ben and Jen could have some alone-time for what appeared to be a serious discussion that began right before they left LA. Ben looked pretty defensive ... was Jen accusing him of something?

Meanwhile, the family was together the day before Thanksgiving as well, going to the local Palisades movie theater to see Frozen 2. Obviously the celebrity parents organized the entire weekend as family time. Other divorced parents, take note!

The Schwarzenegger clan didn't let a little rain spoil their Thanksgiving Day! Arnold visited the Santa Monica Pier, attracting a TON of fans.

Katherine was out at her usual morning Pilates class while mom Maria Shriver and bro Patrick hit up the Brentwood Country Mart. Patrick was flexing in his orange Prada rain jacket, while Maria looked amazing, even in a downpour. Did she get some work done? Seriously, she looks great!
