Michael Jackson's smash hit Thriller is coming back to haunt him - his video girlfriend is suing the King of Pop over unpaid royalties.

Actress Ola Ray, a former Playboy Playmate, has filed suit against Jackson and his production company alleging breach of contract.

According to TMZ, Ray's attorney claims she was promised a cut of the 1983 promo's revenue but has yet to receive a penny.

The epic 14-minute video, which was directed by John Landis, was the most expensive promo of its time, at a cost of $500,000.

Landis also filed suit against Jackson in January, claiming he's owed royalties for his work on the iconic promo and related spin-offs.

In his suit, the director alleged he had a deal in place with the superstar, which entitled him to 50 per cent of the net profits from the video and related material.
