ET has learned that So You Think You Can Dance judge Mary Murphy has been sued by her former manager, Michael Sanchez, for breach of written and oral contract.
According to court documents obtained by ET, Sanchez was hired as Murphy's manager in 2006 and terminated in 2010.
In the court filings, Sanchez says that some of Murphy's actions during their business relationship led him to conclude that "Murphy had become a desperate, cocaine-fueled nymphomaniac."
The papers claim that Murphy took up "many inappropriate sexual relationships with So You Think You Can Dance and Chelsea Lately crew members, as well as other questionable men."
In the lawsuit, Sanchez is seeking more than $1,000,000 in damages after allegedly being fired over a financial dispute. The papers claim that Sanchez's firing was done in a way that breached their contract.
