Leonardo Dicaprio - Lindsay Lohan's Leo Crush

Leonardo DiCaprio is Lindsay Lohan's "perfect man".

The actress - who has an on/off lesbian relationship with DJ Samantha Ronson - reportedly has a crush on the 'Departed' actor , but friends don't believe he is interested in pursuing a romance with her.

A source said: "Lindsay has a major crush on Leonardo but that's as far as it goes right now.

"She knows him, they are friends but that's it. Lindsay is ready to be more then friends with Leo but he doesn't see her that way. She's says he's her perfect man but fears he doesn't take her seriously."

The couple were romantically linked earlier this year when the 'Mean Girls' star desperately tried to get the 'Revolutionary Road' hunk's attention at a Hollywood party.

A source explained at the time: "As soon as Lindsay saw Leonardo she was like a bee to honey. When she spotted him in a dark corner of the club she headed straight for him. She quickly monopolised his conversation and made sure she had him all to herself.

"They talked and Lindsay danced in front of him but nothing happened. They went home separately."
