Lori Loughlin and her husband have pleaded not guilty in what authorities have described as the largest college admissions scam ever prosecuted by the US Justice Department.
The pair said in court documents filed on Monday that they are waiving their right to appear in court for an arraignment and plead not guilty.
Loughlin, Giannulli and more than a dozen other parents were indicted last week on charges of mail fraud and money laundering conspiracy.
The couple are charged with allegedly paying $500,000 in bribes to get their daughters admitted to the University of Southern California as crew recruits, even though neither is a rower.
They haven't publicly addressed the allegations against them.
Several other indicted parents have also entered not guilty pleas.
Fellow actress Felicity Huffman and 12 other parents have agreed to plead guilty.
Loughlin and Huffman were first charged in the case in March, when federal prosecutors charged 50 people following an FBI investigation.
