Daniel Radcliffe fell in love with his girlfriend the most AWKWARD way

If Daniel Radcliffe and his girlfriend, actress Erin Darke, end up settling down and having kids, they're going to have a VERY weird "how I met your mother" story. 

In an interview with Playboy, Daniel revealed that the loved-up pair first got together after they filmed a sex scene (TMI, Daniel).

Daniel and Erin met on the set of Kill Your Darlings, in which he played Allen Ginsberg in Columbia University. 

And while the movie generated a lot of buzz for his gay sex scene, it was another one with Erin that changed his life. 

(Does anyone else think Harry Potter is officially gone now?!)

In one sexy/mostly awkward scene, Erin's character, Gwendolyn, comes on to Allen in the library.

"That's a wonderful record of us both flirting for the first time," said Daniel.

"There's no acting going on – not from my end anyway," he said, explaining the the connection between them was genuine from the start. 

"There's a moment when she makes me laugh, and I'm laughing as me and not as my character."

"She was incredibly funny and smart. I knew I was in trouble."
