The big game is on Sunday — which means lots of beer, snacks, hoo-ing and haw-ing, and ... Kim Kardashian, natch!

The reality TV queen will appear in what looks to be a racy ad for Skechers Shape-Ups during the fourth quarter of the Steelers/Packers game. Watch a sneak peek below!

"I don't want to give too much away," Kim says of the ad, which features her arms around the neck of a sweaty hunk, "but it's pretty provocative. It's fun, it's sexy — and let's just say that I break someone's heart. So it was, like, so easy to do, so easy to shoot. Just kidding."

"Kim had a lot of fun with the racy and somewhat tongue-in-cheek theme of the commercial," a source tells People. "It was a long day on set, but the finished product … was definitely worth the effort."

The commercials during Sunday's game will be star-studded — in addition to Kim’s ad, the Biebs will be featured in an ad with Ozzy Osbourne for Best Buy (huh?) and Faith Hill will be in an ad for TeleFlora. Random.
