Actress Lori Loughlin pleaded not guilty Monday to federal charges that she laundered money in a complex scheme to buy her daughters' way into college.

The "Full House" actress and her fashion designer husband, Mossimo Giannulli, who are both free on bail, waived their right to appear in a Boston courthouse and allowed defense lawyers to enter the not guilty plea to all charges, according to papers filed Monday.

Loughlin, 54, and Giannulli were charged last month with conspiracy to commit mail fraud for allegedly paying bribes totaling $500,000 to help their two daughters get into the University of Southern California.

The new superseding indictment, made public last week, adds the charge of money laundering against the couple and 14 other defendants accused in the scheme.

Federal authorities accused parents of funneling bribes and other payments through a purported charity and for-profit corporation, and transferring money from outside of the United States into the country "for the purpose of promoting the fraud scheme."

Loughlin is best known for playing Aunt Becky on the long-running sitcom "Full House." She was also a part of that show's reboot "Fuller House."
