Matthew Mcconaughey would have made a move on co-star Kate Hudson if she wasn't married when the couple made HOW TO LOSE A MAN IN 10 DAYS. The movie hunk was quizzed about his feelings for Hudson by the actress herself during a recent TV interview to promote the pair's new film Fool's Gold - and he confessed he had a crush on her while they were making the 2003 romantic comedy. Hudson asked, "Do you think if I hadn't been married (to Chris Robinson) on How To Lose A Guy, you'd have gone in for the kill?" A visibly stunned MCConaughey paused before confessing, "If we were both single back then, sure." Hudson admits she and MCConaughey often behave like a married couple when they're working together. She adds, "We can tell each other when we can't stand each other. I can run and grab him and go, 'I love you so much' and then I could tell him he's driving me crazy."
