Leonardo Dicaprio is reportedly dating Australian model Alyce Crawford.

The 36-year-old actor - who announced his split from Blake Lively this week after five months of dating - has been cosying up to Alyce, 21, for the past few weeks while shooting 'The Great Gatsby' in Sydney.

A source told Australia's Daily Telegraph newspaper: "It's been going on about two weeks. He texts her when he wants to see her and they hook up a few times a week. They've mostly been meeting up during the week. He does other things on weekends.

"She's been going to his hotel to visit but he is too smart to be seen with her in public."

Although former 'Australia's Next Top Model' contestant Alyce denied romancing the actor, she did admit describe him as a "lovely, lovely guy" and confirmed the pair have been hanging out together.

She said: "We have a lot of mutual friends and he seems really nice. We're just friends.' "

Leonardo and Blake's split came as a surprise after friends of the actor revealed he was smitten with the actress saying they had "never seen him like this with a girl".

Another friend added: "'I bet they get engaged in six months."
