Actor Ashton Kutcher has promised to return to modelling if his new movie 'A Lot Like Love' tops the box office.
According to ABC News, Kutcher told 'Access Hollywood' that he would model Calvin Klein underwear if the movie, which is due to be released this Friday in the US, is the top-grossing film over the weekend.
"If we are the number one movie in America, I will do a Calvin Klein underwear campaign," the actor said.
Kutcher, who began his career as a model, made the promise as part of a bet with his producing partner.
'A Lot Like Love', which also stars Amanda Peet, tells the story of a couple over a seven year period.
His current movie 'Guess Who' opens in Irish cinemas this weekend.
