Carrie Fisher lost her virginity to her friend Griffin Dunne - even though she had a boyfriend at the time

Griffin told the New York Post newspaper's Page Six column: "I was doing her a favour. She had a boyfriend and she didn't want him to know she was a virgin and she trusted me and gave me the honour."

But despite the clinical nature of the arrangement, the 68-year-old actor insisted they were both "into it".

He said: "We were into it. We had a few practice sessions.

"Look at her, she was gorgeous! I couldn't have been luckier.

"[I was] hardly Casanova, but I was a tad more experienced."

The 'Girls on the Bus' actor stayed in contact with the 'Star Wars' legend until she died in 2016 at the age of 60.

He said: "We had a core group of friends."

The friendship circle still have a group chat where they regularly share "a memory" of their late pal.

Griffin said it contained: "An irreverent filthy story or the funniest, most unpublishable things you can imagine."

Before he became an actor, Griffin was keen to be a writer or a journalist, but he got expelled from high school after being found smoking marijuana.

He explained: "I was in Colorado in a boarding school and I got caught smoking pot."

And the 'After Hours' actor noted he was unlucky the incident didn't happen a few years later.

He added: "Colorado, by the way, was the first state to legalise pot, so my timing was a little off."
