Where isn’t the Jersey Shore popping out these days? We didn’t think it would be on Kara’s head!

Jersey Shore is literally taking over the world, one step at a time. In addition to appearing on Lopez Tonight and the Tonight Show March 3, one part of the Jersey experience cropped up where you’d least expect it: on American Idol!

But before you start thinking that Pauly D was performing or The Situation was giving his best Simon Cowell, we have to steer you in a different direction. Nicole ‘Snooki’ Polizzi actually made a guest spot on the show – when judge Kara DioGuardi wore her signature hair poof, that is.

Snooki noticed that Kara, 39, was rocking her look, too – and she liked it! “So proud! Met her at the grammys! She’s great :)” the 21-year-old wrote on her Twitter page Wednesday night in response to a fan comment reading, “Kara Dioguardi is so rockin the @sn00ki tonight.”

FYI, Kara. We’ll all be watching to see whether or not you’ll be fist-pumping on tonight’s elimination episode!
