Jon Hamm carried a jacket, but certainly didn't need one, on his way to a meeting in the headline-making heat that hit LA yesterday. The actor has been growing back his off-season beard lately, while on Mad Men his usually cool and collected Don Draper is unraveling. The latest episode featured a panic attack amid the drama of the sexually liberated '60s. This season is already sadly winding down, but lucky for us there's a lot more Jon Hamm coming our way. He'll be showcasing his comedy chops on the Oct. 14 live episode of 30 Rock, and will return to host SNL on Oct. 30.

The boys of 90210 stripped off their wetsuits on the set of their show in LA yesterday. Matt Lanter's sexy six-pack has been a welcome sight while filming scenes this season, and Tristan Wilds got into the shirtless action after hitting the waves with his buddies. Michael Steger's Navid sat out the surfing session as usual, though we did get a peek at his abs during his scandalous True Blood guest-starring gig last month.

She'll have to take a break to promote The Tourist before its December release, and Brad has his own project coming out this Fall.

Katie Holmes swapped out the more casual dress she wore earlier to check out the Calvin Klein runway show for a white strapless number and towering heels as she stepped out of her hotel in NYC last night.

Her fellow cupcake-loving daughter had a low-key evening, but Katie's motorcycle happy husband, Tom, was spotted rushing back home yesterday as well.

Britney is moving on from last week's drama surrounding a former bodyguard who accused her of sexual harassment, though she still has rumors to shoot down. She issued her latest "BS Report" about a story saying she got engaged during her recent vacation in Hawaii with boyfriend Jason Trawick. Most of you think wedding bells are in the cards for Brit and Jason, but apparently not quite yet.
