Jason Segel had his hands full when he returned to his LA home yesterday afternoon with laundry and a new tote from Lauren Bush's FEED line. He was fresh off a stop recording an interview on The Tonight Show to promote his new comedy The Five-Year Engagement, and he had his iPhone in hand. The gadget had an interesting bit of personalization — on the back was a photo of his girlfriend Michelle Williams, with decorations that read "I Love You." Jason Segel and Michelle Williams are dating and apparently have been for a few months, after being set up by mutual pal Busy Philipps. Jason and Michelle had a date night in Brooklyn last month that was captured in photographs, finally making their romance public for fans.
