It was obvious Gerard Butler had been losing some weight, but it wasn't until he shed his shirt after a charity soccer match
that the extent of his efforts became clear.
Butler, 41, showed off his newly ripped abs and chiseled arms to go with his shock of blond hair Tuesday, all part of preparing for the surfing movie Mavericks
, while also goofing for the camera by sticking out his tongue.
Not only does he look good, but it's helping his game. His team won 5-2 in a game benefiting Oxfam.
