Gentlemen, start your engines!... Israeli supermodel Bar Refaeli is spectacularly single.

People.com just announced that the 23-year-old Sports Illustrated covergirl and Leonardo DiCaprio are taking a break from their nearly three-year-long relationship, and that HE did the dumping!

A source tells People: "She wanted to move faster than he did, she wanted to move in together, so he broke it off."

Apparently Leo, 34, was seen chatting up another girl in a New York nightclub last week. Says People's source: "He was standing at the bar in front of everyone talking to a girl the entire night – and it wasn't Bar. It was in no way behavior for a guy who has a serious girlfriend."

So, now that we've established that Leonardo DiCaprio is completely insane, please take a look at these gratuitous pictures of Bar Refaeli in an 'almost-there' pink bikini...

       

Israeli supermodel Bar Refaeli gave us the gift of her her hotness yet again, as she plugged the new Reebok trapeze fitness system, Jukari Fit To Fly, on the roof of the Circulo de Bellas Artes in Madrid, Spain. Must've taken hours to prepare those underarms for their public!

Cabo was definitely a hot spot for celebs to ring in the new year.  We spotted Leonardo DiCaprio and super model girlfriend Bar Refaeli enjoying themselves in the Mexican resort town over the weekend.

Leo's next film will be Shutter Island which will be released in October.  Set in 1954, Leo will play U.S. Marshal Teddy Daniels, who investigates the disappearance of a murderess who escaped from a hospital for the criminally insane and is presumed to be hiding on the remote Shutter Island.  Co-staring Mark Ruffalo and Michelle Williams, Shutter Island is one of the most anticipated movies for 2009.

     

We spotted Bar Refaeli enjoying herself on the sands of Saint Tropez.  The supermodel swam with friends and then covered herself up in a floral romper.  Leo DiCaprio is one lucky dude.
