Jake Pavelka is getting ready to start his new job as the host of the bare-chested Chippendales show in Las Vegas and he exclusively told RadarOnline.com that not only is he terrified about the live audience, but he’s been told his job is to “get the girls into their underwear!”

A hunky alum of the reality show The Bachelor, Jake is making his debut appearance with the Chippendales on February 23 at the Rio All-Suite Hotel and Casino, and he says he’s afraid of going out on stage.

Jake Pavelka is a stripper?

The former Bachelor star has a new job with the bare-chested Chippendales in Las Vegas, and while he’ll be on stage with the hottest guys around, much to the disappointment of his fans, he won’t be going the full monty.

The hunky reality star, whose breakup with Vienna Girardi has been a nasty battle played out on TV, will “use his charm, sex appeal and hosting skills to keep the women entertained while leaving the dancing to the men of Chippendales,” according to the show’s publicist.

It looks like Ronnie Ortiz-Magro could have a career as a dancer when those Jersey Shore days are over.

The reality star was in Vegas Saturday night to guest host the Chippendales show at the Rio, and RadarOnline.com has the pictures.

Ronnie clearly enjoyed the experience, getting into the spirit of things by stripping down and joining the dancers onstage, much to the delight of the audience.

And because Ronnie has a new t-shirt line called "Jersey Laundry," the Chippendale dancers wore his T-shirts during one number while he wore one of their costumes.

We're sure Mike 'The Situation' Sorrentino is very jealous!
