Leonardo DiCaprio has fuelled rumours he’s back together with on-off girlfriend Bar Refaeli after they spent most of New Year’s Eve locked at the lips.

The pair, who were rumoured to have split in the last September, started the evening in the Poker Room of the Bellagio in Las Vegas but even though they were gambling at separate tables, a source told the New York Post that Leonardo couldn’t stay away from the Israeli model: “Leo came over to her table, cupped her cheeks with his hand and planted a kiss on her.”

The couple later moved onto the hotel’s club, The Bank, to celebrate the new year with a group of friends.

An onlooker told Us Weekly that at the strike of midnight, they “shared a long, passionate kiss” then drunk champagne before hitting the dance floor: “they danced for a couple of hours but were kissing constantly.”

The pair left the club “hand-in-hand” around 2.20am.
