Sorrentino, who also starred in the UK version of Celebrity Big Brother, was charged with simple assault after the afternoon confrontation at the Boca salon in Middletown Township, which he and his family own and operate.
He posted 500 dollars' (£295) bail and was released. A court date has not been scheduled.
Police went to the salon at around 2pm following a report of a fight in progress, said Detective Lt Stephen Dollinger.
The incident is interesting timing, as Sorrentino is due to return to reality TV this summer in the TV Guide Network's The Sorrentinos, which will follow his family as they try to open their own tanning salon.
The cast members of MTV's Jersey Shore, filmed in Seaside Heights, were known for their love of tanning and the motto GTL - gym, tan, laundry. They also were known for a rowdy, partying lifestyle that resulted in some cast members getting in fights and other facing legal troubles for alcohol-related incidents.
In an interview last September, Sorrentino said he had gone through rehab for an addiction to painkillers.
