The Jersey Shore cast will undoubtedly be the most popular Halloween costumes this year, what with Snooki‘s Bump-It and all — but what will the cast of MTV‘s Jersey Shore be dressing up as for Halloween?

Snooki shared her ideas on last week’s The Wendy Williams Show:

“I was thinking of being a sexy pickle,”

Or, if that doesn’t work, Snooki says she may like to be this season’s other most popular costume: Lady Gaga.

What about Pauly D? Turns out, he’s got the Bieber fever real bad this Halloween and will be dressing up as Justin Bieber.

He told PEOPLE:

“I never wear my hair down ever, so it will be the first time in my life I ever deejay with my hair down.”

“I got Bieber Fever!”

The lead man, Mike ‘The Situation’ Sorrentino, is planning to be a party pooper for Halloween, because he has no plans to dress up — though he will be in Vegas surrounded by lots of girls who will be dressing up. So I guess his costume is someone that people care about? A pimp?

What will you be for Halloween?
