The former football coach at the University of Southern California faces charges for creating fake sports profiles for Lori Loughlin's daughter and other wealthy parents' children.
Laura Janke, a former USC football coach, pleaded guilty to her role in college college scams.
Prosecutors announced that Loughlin and her husband had paid Singer $ 500,000, which had offered USC officials to name their two daughters as fictitious crew recruits.
At the request of Singer, Janke created in 2017 a profile describing the girl, Olivia Jade Giannulli, as a competitive rower, even though she did not participate in the sport, according to the government.
Prosecutors said the YouTube star and his influence on social media had finally been admitted to the USC as a team rookie.
Although his charge carries a maximum penalty of 20 years imprisonment, prosecutors will seek a sentence of 27 months to 33 months imprisonment.
