Former "Jersey Shore" reality series star Mike "The Situation" Sorrentino is facing several federal tax charges.

Sorrentino and his brother, Marc, are named in a seven-count indictment released Wednesday by the U.S. Attorney's Office.

Prosecutors allege the brothers failed to pay all taxes owed on nearly $9 million earned from various business ventures over the last four years.

They're charged with conspiracy to defraud, several counts of filing false tax returns and one count of failing to file taxes.

The cast of the MTV reality show were known for their rowdy, partying lifestyle that sometimes led to legal troubles. In July, Mike Sorrentino agreed to take anger management classes to resolve assault charges he faced following a July 15 fight with his brother at their family's tanning salon.
