James Leonard Jr., who represents Sammi "Sweetheart" Giancola, says he spoke with her Tuesday after a woman accused the reality show star of punching her twice in the head Saturday night.
Kristen DeMinco showed reporters a bruise under her eye during a news conference outside Miami Beach police headquarters.
Leonard would not go into detail about what transpired between the women. He says he expects Giancola to be cleared once all the facts are known.
A spokesman for the prosecutor's office said authorities would review the allegations to see if charges are appropriate.
"Jersey Shore" is filming in Florida, but will return to Seaside Heights this summer.
