A little bit of the Jersey Shore will come to the CW’s 90210 this autumn. EW has learned that Vinny Guadagnino has been cast in an episode that will air in November.

Guadagnino will portray a celebrity who plays in a high stakes poker game with Liam (Matt Lanter) when the cast heads to Las Vegas. He won’t play himself, however: He’ll depict a “young and gregarious” celebrity who “enjoys the fruits of fame.” Earlier this month, the show put out a search for a celeb who “could be anybody from an upcoming movie star to a well-known reality TV personality.”

90210 wanted casting agents to submit well-known names only — thus, the arrival of Vinny!

Thrilled to see an MTV reality star on the CW?
