The actor, who has previously dated supermodels Naomi Campbell and Helena Christensen, hopes that he will soon be able to ditch his playboy image and find love.

"When you're my age and your hormones are kicking in there's not much besides sex that's on your mind," Leonardo told the News of the World. "I do believe in love at first sight, though it hasn't happened to me yet."

He added: "I've never been a Romeo who meets a girl and falls for her immediately. It's a slower process for me. I've always been a slow starter."
