Lily Allen thought Mark Ronson was gay when she first met him.
The 'Smile' singer - who collaborated with the producer on a cover of the Kaiser Chiefs' hit track 'Oh My God' - admits she was stunned when she found out Mark was heterosexual.
She said: "I met Mark at a club night in London called YOYO. I thought he was cute, but assumed he was gay. I remember being shocked when I was introduced to his girlfriend at the time!
"Mark is magnetic in the sense that people are just drawn to him. He is also sickeningly good at working a room - women love him as do men."
Mark - who recently split from British model Daisy Lowe - also revealed he doesn't think he should be as famous as he is, because all he does is "bring different types of people together".
He told Paper magazine: "If you could call that a talent, that is probably one of my main ones, I would imagine. I enjoy when different people bring something out of each other that they usually wouldn't - when the combination of two things make something new, exciting, worthy and different."
