Bar Refaeli: 2012 Oscar Party-Hopping Beauty

The March 2012 cover of Interview Magazine leaked online earlier today (February 27), and it revealed a dramatically different looking Katy Perry on its front page.

The "Part Of Me" singer shed her usually playful, girly self for the black and white spread, unveiling a very Amy Winehouse-like seduction in the pose.

In the snapshot, the 27-year-old is dons a blinged out bra top with long black gloves and dangling diamond earrings.

After offering up the sneak peek of their latest celeb-fronted issue, the mag released a statement about it on their site, reading, "If you haven’t already heard, Katy Perry is our March covergirl. We’re pretty excited (!), especially as she’s interviewed by one of our favorite comedians, Kristen Wiig. Above is a sneak peek of Katy’s cover, shot by Mikael Jansson and styled by Karl Templer. More to come later in the week..."

Living it up at one of the biggest events of the year, Bar Refaeli took part in the offerings of the annual Oscars on Sunday (February 26).

The Israeli model dazzled in a floor-length gown as she posed for pictures during Vanity Fair’s Oscar party held at the Sunset Tower in West Hollywood.

Earlier in the evening, Ms Refaeli and the newly-single Heidi Klum playfully looked back at one of the photographers and patted each other’s backsides while making half seductive half silly faces at the camera.

Posting the eye-popping photo to her own Twitter account, Bar wrote, “LOL. Put 2 fun girls together, and this is what u'll get!”
