Ashton Kutcher thinks one-night stands are ''gross.'' The
Two and a Half Men star - who recently got engaged to his former
That '70s Show co-star Mila Kunis - thinks it can be ''fun'' not to be attached to anyone, but eventually single life gets tiring. He told
Men's Fitness magazine: ''Being a single guy can be a lot of fun... when you're financially independent [and] can do whatever you want, whenever you want... For every girl you have a good time with for one night, if you want to stay single, that's the same girl that you have to not call back. After a while, being the one-night-stand guy is also just a little gross.'' The 36-year-old actor began dating Mila after his marriage to 51-year-old
Ghost actress Demi Moore broke down following Ashton's one night stand with a random girl.
