Leonardo DiCaprio’s on/off supermodel girlfriend Bar Refaeli has replaced his former flame Gisele Bundchen — reportedly expecting her first baby with new husband Tom Brady — as the new spokesmodel for Rampage Clothing.

The Israeli-born Sports Illustrated stunner sat for a series of sexy new snaps promoting Rampage’s fall collection.

Sports Illustrated swimsuit model Bar Refaeli is appears nude in a new steamy campaign promoting an art exhibition in her native Israel.

In the erotic black and white clip, currently making the rounds online, the 24-year-old model writhing around on a sofa with a sheet covering her bare body.

On-again off-again couple Leonardo DiCaprio and Bar Refaeli are off once again, sources confirm to PEOPLE.

The 23-year-old model, who covered this year’s Sports Illustrated Swimsuit, reportedly made her split from the 34-year-old Titanic star official at last weekend’s 11th Annual Young Hollywood Awards stag.

“They’re taking time off for the time being, they’ve split,” says a source. “It could just end up as a break but for now they’re doing their own thing.”

A nude Bar Refaeli covers the July 2009 issue of Esquire Magazine with the opening lines of a new Stephen King story, “Moriarty,” painted on her naked body — a first for the mag.

“I walked along dirt roads and picked oranges and played with dogs and rabbits and chickens and horses,” the Sports Illustrated Swimsuit Issue covergirl. “Israel is so small. Israeli girls are a little more – I’m not comparing – but we’re very confident. We like to have fun. We’re very free. It shows in our character, and it goes in the camera.”

Israeli model Bar Rafaeli appeared on The Ellen DeGeneres Show to promote the 2009 swimsuit issue of Sports Illustrated on Friday, Feb. 20.
