Israeli model Bar Refaeli is in the sex appeal business and she’s got plenty to go around. She does a sexy strip for a new Santa-themed commercial for her underwear line “” She knows how to strut her stuff.

Refaeli, 27, launched the line in May with a sexy video that left little to the imagination. She appeared in it almost nude.

“My secret is living a healthy lifestyle,” she said at the time. “Also having a sense of humor about life, taking things easy – it’s a big part of the way you present yourself.”

Her philosophy is evident in her latest commercial. Bar walks through famed Central Park in Manhattan wearing a Santa suit and beard that obscures her identity and knockout body.

Ironically, Refaeli is Jewish. But that doesn’t dampen her spirit for Christmas. She draws lots of odd stares on her long walk home but not because she’s a supermodel.

When she gets home, she starts to unwind, shaking her head, tousling her hair and peeling off her Santa suit seductively. A hunk in another apartment has a clear view through her open window, but she doesn’t seem to mind.

She struts arouind wearing only her Santa jacket and ends up in the bedroom, wearing a white sleeveless top, pajama bottoms and her Santa hat. She gives a knowing wink before the commercial ends.

She released the video today (Dec. 13) and tweeted a link with the message: “Santa Claus is coming to town! Merry Christmas!’
