Transformers star Shia Labeouf fears his downfall lies in the lure of beautiful women - because he can't stay away from the opposite sex.

The 21-year-old doesn't have a longterm girlfriend and is happy to enjoy the benefits of being a young, single actor in Hollywood.

And LaBeouf is convinced the best thing about being the star is the constant throng of female admirers.

He says, "I have my vices and that includes women. Not that I have time for relationships as such, but that doesn't mean I have to live like a monk, right?"

"As vices go, women are right up there with my favorites. In fact, women are probably the best vice in the world."

"I try to be respectful but sometimes women are looking for more commitment than I'm able or willing to give. I can't commit myself to one woman for any length of time. But I love their company intensely."
