"So You Think You Can Dance" judge Mary Murphy was hit with a lawsuit filed by her ex-personal manager Michael Sanchez, and he's claiming that Murphy lived a dangerous life fueled by coke and "many inappropriate sexual relationships with 'So You Think You Can Dance' and 'Chelsea Lately' crew members."

The guy worked with Murphy for four years before she fired him in 2010. He also claimed that the TV host fell into a bad downward spiral, becoming "increasingly self-absorbed, childish and demanding" over the years.
A source sas, "Mary is the ultimate 'victim'. Whenever something goes wrong, even if it's her fault, she will blame someone else.
"She never takes credit for the diastrous choices she makes."
