Bristol Palin is teaming up with Mike "The Situation" Sorrentino for a hilarious new PSA to prevent teen pregnancy.

In the video (watch above), he tries to hit on the teen mom, 20, but she rebuffs his advances.

"I know you're all about that abstinence thing, but come on, B-Palin, are you serious? You're not gonna hook up before you're married? For real?" he asks.

"For real," she insists.

Though he may bed different babes, he tells her she has no need to worry about him and pulls out Magnum condoms to prove he practices safe sex.

"Well, I am glad we agree on one thing," she tells him. "Pause before you play."

"Pause before you play," he responds, "that's probably the most important thing."

Palin has been promoting abstinence as The Candie's Foundation's Teen Ambassador for the past year-and-a-half. Sorrentino, 28, says he became involved because "it's an important cause and I am proud to be a part of it."
