Why can't people just behave themselves? Mad Men star Jon Hamm and his girlfriend, writer/director/actress Jennifer Westfeldt were in London earlier this month promoting their film Friends With Kids when they were reportedly robbed.

"They were dining at a restaurant and Jennifer's purse was snagged by someone," a source tells Life & Style. "That person took the hotel key in Jennifer's purse, which had the hotel name on it, and robbed their room. They had to contact the police, it was horrible."

Not sure why that "source" had no name, but Jennifer confirmed the news to Life & Style at Tropfest New York on June 23. "What a mess," she said. "[I'm not feeling] great. It is under investigation."

Come on! Nobody steals from Don Draper. It's his job to steal from others. (Just ask Peggy Olson. And the real Don Draper.)
