Former “American Idol” and “So You Think You Can Dance” producer Nigel Lythgoe has stepped down from the competition dance show amid Paula Abdul suing him for alleged sexual assault.

“I have informed the producers of ‘So You Think You Can Dance’ of my decision to step back from participating in this year’s series,” Lythgoe, 74, told TMZ on Friday.

“I did so with a heavy heart but entirely voluntarily because this great program has always been about dance and dancers, and that’s where its focus needs to remain.”

He concluded, “In the meantime, I am dedicating myself to clearing my name and restoring my reputation.”

The Post has contacted reps for Lythgoe, Abdul, and Fox for comment.

Lythgoe has denied the “Straight Up” singer’s accusations but has also been accused by two more women of sexual assault and battery that allegedly happened in the early 2000s.
