OK, he was legal and everything, but there's still something really icky about this.
Daniel Radcliffe just admitted that he lost his virginity to a "much older woman" at the age of 16!
Now he's turned into a grown-up 19-year-old hunk who's about to start getting naked on a Broadway stage every night in Equus.
But that was around the time he was filming the fourth movie, Harry Potter and the Goblet of Fire -- surely the only reason any older woman should have had her hands on him would have been to ruffle his hair or straighten that little school tie of his.
Daniel wouldn't reveal the exact age of his first-time cougar.
But he said in the latest issue of Details magazine that although the age difference "wasn't ridiculous" it would definitely "freak some people out."
The Brit star also told the magazine that he's single right now because there's no time in his life for a girlfriend.
"Most of my friends have been girls and I see how they are with their boyfriends and I think 'I couldn't do that,'" he said.
"I just don't have the time."
