When Anne Hathaway was on Late Night last October, David Letterman grilled her about her ex, Raffaello Follieri. Last night Kate Hudson visited, and Dave brought up Follieri again:

Kate explained that Anne is her costar in Bride Wars, and Letterman quipped, "She's nice, isn't she? I think her old boyfriend is in prison." Kate tried to change the subject and tactfully maneuver around Letterman's jabs, but admitted that she watched when he grilled Anne about Follieri. "I was like, 'Oh, you're giving it to her," Kate told Letterman. And just when things seemed to die down, Letterman mentioned how Follieri dressed up as the Pope. Clip above.
