Britney Spears looked pretty cute leaving a meeting at the William Morris Agency offices in Beverly Hills yesterday. As we watch and cheer on her improvement, fans are eagerly awaiting her next big comeback project. As one producer is claiming to be helping Brit reinvent herself musically, there's apparently another aspect of Brit that hasn't changed. Rumor has it she's been back in communication with Adnan — yes that Adnan — though Brit's dad is trying to stop the two from talking. Her paparazzo ex only ever seemed like bad news, blech, so here's to hoping that she's not still involved with him in any way.

Last year Matt Damon and Ben Affleck celebrated their holiday weekend with a BFF family trip to Hawaii, and this year they were back together for a different reason. The Boston boys showed off their skills, along with friends like Adam Sandler and Don Cheadle, at the 2nd annual Ante Up for Africa charity poker tournament in Las Vegas last night. From the looks of those big smiles, they didn't have a problem whether they were losing or winning, it was all for a good cause. We know that the crises overseas are so important to both Matt and Ben, but it's always nice to add a little bit of fun into dedicated philanthropy.

It was another dress up day for Heidi Klum and her kids in NYC yesterday. Heidi didn't have a costume on, but she looked hot all glammed up for a photo shoot and lunch with friends at Barbuto. Leni went with one of her best pink princess ballerina outfits, while Henry and Johan were happy to take the scenic tour from their personal modes of transportation. Even if the family couldn't spend the whole day together, they still manage to look adorable going their separate ways.

Ashlee Simpson and Pete Wentz left their furry baby Rigby at home and headed into a doctor's appointment in LA yesterday. Ash seems to be in the mood to match her maxi dress to her hair in orange again. Seriously though, between his glasses and her wayfarers, could their eyewear be any more hipster? The tattoo loving couple has many months to go before their new addition, but rumor has it that they were seen shopping for lots of blue baby things. Of course, the news comes from Petit Tresor so take it with a grain of salt — plus, when it comes to unconventional Pete and Ashlee I'd say that nursery color doesn't necessarily mean we know we're expecting a boy.
