What's up with Brad Pitt's gnarly-looking facial fuzz?
"It's boredom. No other reason than that," the actor, 46, tells Britain's Sun newspaper.
On Monday, a solo Pitt, 46, was in London to promote the action-thriller "Kick-Ass" (out April 14), which he helped produce for director Matthew Vaughn, who is married to pregnant supermodel Claudia Schiffer.
Pitt has since returned to Venice, where his self-described "soul mate" Angelina Jolie is shooting "The Tourist" with Johnny Depp.
Asked how his time has been there, he told UsMagazine.com: "Lovely!" On Tuesday, Pitt and Jolie, 34, showed off a rare glimpse of their 20-month-old twins Vivienne and Knox while relaxing on the private balcony of the 15th century palazzo they're renting.
