Leonardo DiCaprio had a boys' day with Lukas Haas and Rick Salomon, hitting up the Prada store. While Lukas is Leo's constant companion, his other good friend and co-star Kate Winslet recently talked about what it was like to get back to work with him on the set of Revolutionary Road. When asked about doing a sex scene with her husband directing, she said, "I just kept saying, 'This is too . . . weird.' And Leo was like, 'Oh, get over it.' And I'm going, 'Yeah, a little reminder: You're my best friend. He's my husband. This is a bit weird.'" Kate also said that she and Leo quickly found their Titantic chemistry again, so we'll look forward to seeing the BFFs reunited on the big screen in January.

Katie Holmes had a very special companion for her morning walk to rehearsal today — her husband Tom Cruise. The actor finally joined his girls in NYC, and it looks like it immediately put a smile on recently slightly gloomy Katie's face. She also left Tom's jeans for him to wear as the duo grasped hands for the stroll. After another late night out with mom, Suri skipped the trip, but we've got many months of seeing the family in NYC ahead. Meanwhile, Tom's people seem to be on the offensive combating any rumors of career trouble for the actor by assuring us that he already passed on Edwin A. Salt long before Angelina's name came up, while chief execs at United Artists released a statement saying Tom isn't going anywhere after the departure of Paula Wagner. Plus, everyone loves him in Tropic Thunder, right?

While John Mayer skipped town when the news of their breakup hit, Jennifer Aniston comforted herself with a little shopping at Edwards-Lowell fur boutique in Beverly Hills yesterday. That's not all she's doing to get her mind off the breakup — she was apparently already seen out on a date with a new man. While it sounds like she might have orchestrated the hot guy sighting to curb any rumors of a broken heart, we can narrow down the list of suspects by one. Matthew Felker, Selma Blair's ex and the star of Britney's "Toxic" video, denied that he is dating Jennifer.

Just a couple of days ago, Lindsay Lohan was publicly voicing how much she missed Samantha, and last night the ladies were back together for the grand opening of the Apple Lounge in LA with the likes of the Hilton sisters. Lindsay showed off her fabulous and more natural hair color, while Samantha seemed insistent on keeping her grouch face plastered on. It might not have been an act for the cameras considering Lindsay's ex-boyfriend Calum Best, of the infamous sex tape rumors, was also hanging around. While Samantha is long used to the gossip about her relationship, it can't be fun to hear rumors that Lindsay's been flirting with boys all over town.
