Los Angeles, May 2 (IANS): Actress Carey Mulligan says she did not have a crush on her "The Great Gatsby" co-star Leonardo DiCaprio when she was a teenager, even though he was a hearthrob back then.

In "The Great Gatsby", directed by Baz Luhrrman, Mulligan has filmed numerous steamy scenes with DiCaprio. She admits she wasn't one of the many young girls who succumbed to the the actor's good looks when he made a name for himself with 1997 film "Titanic".

"Well, he wasn't my pin-up, but he was for a lot of my girlfriends. Michael Schumacher (was my pin-up). I used to watch Formula 1 with my dad when I was little," femalefirst.co.uk quoted Mulligan as saying.

The 29-year-old, who plays heartbroken Daisy in "The Great Gatsby", said she still couldn't help but give in to the actor's charm when she auditioned for the role for the forthcoming project.

"When I did the audition with Leo in New York I walked away grinning. Just the idea that if I never got any further, I had just spent an hour and a half acting with Leonardo DiCaprio," she said.

"I was terrified of reading with him, but it said in the script that Daisy kisses Gatsby so I asked if I should and (director) Baz (Luhrmann) said yes, so I kissed him," she added.
