You’re no Mariah Carey!

Jenni “JWoWW” Farley supposedly turned up her nose at the Cadillac Escalade sent to bring her from Long Island to the Estate club in Boston last weekend.

“First she made the car wait 45 minutes,” says a source. “Then she told the driver she doesn’t travel in Escalades.”

Estate then made arrangements for a limo to come get the Jersey Shore cast member!

Is she effing serious? These Jersey Shore kids are getting a little TOO big for their britches — tone it down a notch, girl!
