Twenty-two year old Harry Potter star Daniel Radcliffe has revealed a lot about his past.  First there were his struggles with alcoholism, and now we learn he has had one-night stands with fans!

“I was always very nervous about the groupie thing. I like to like somebody before I sleep with them. You know, you’re going to have to talk to them afterwards, even if it is a one-night stand,” Daniel shared in an interview with the Daily Mirror.

“I have… I mean, that [one-night stand] has happened, but generally speaking I’ve known the person. Apart from a few times when I was drinking.”

Those days are behind Daniel now.  After too many blackouts, the actor stopped drinking and is 18 months sober.  He is in a committed relationship with longtime girlfriend Rosie Coker – they’re going a year strong!  And while he will miss Valentine’s Day with his lady to promote The Woman in Black, he has three weeks of vacation coming up which they plan on spending together as a couple.
