Jersey Shore star Nicole "Snooki" Polizzi pleaded not guilty Wednesday to charges of disorderly conduct, creating a public nuisance and annoying others on a public beach, according to The Associated Press.

The three charges, the last of which was added by prosecutors on Wednesday, stem from Polizzi's July 30 arrest. The 22-year-old was taken into custody after beachgoers claimed she was bothering them, Seaside Heights police Chief Thomas Boyd said.

She was released on a summons later that day.

Polizzi did not appear in court Wednesday. A second hearing is scheduled for Sept. 8. If convicted of all three charges, she would face about $500 in fines.

Polizzi's co-star, Ronnie Ortiz-Magro, was arrested Aug. 16 on charges of outstanding warrants from two separate New Jersey townships. Taping for Jersey Shore's third season is currently in progress.
