Leonardo DiCaprio is back on the market

Leonardo DiCaprio and Blake Lively have broken up after 5 months together.

The couple, who were first linked in May at the Cannes Film Festival, are thought to have split because of work commitments.

‘It's amicable. They're friends,' a source tells People.

But it seems Gossip Girl star Blake, 24, is already moving on.

She was spotted having dinner at a sushi restaurant with Green Lantern co-star Ryan Reynolds, 34, in Boston last week.
 
Leo, 36, has previously dated Bar Refaeli and Gisele Bundchen.
