Michael Jackson has been accused of yet another case of molestation almost four years after his death.

Celebrity choreographer Wade Robson, who has worked with acts such as 'N Sync and Britney Spears, has filed legal documents accusing the late King of Pop of molesting him as a child.

Howard Weitzman, the lawyer for the Jackson estate, has hit back at the accusations, telling TMZ: "Mr. Robson's claim is outrageous and pathetic. This is a man who has testified at least twice under oath over the past 20 years and said in numerous interviews that Micheal Jackson never did anything inappropriate to him or with him."

Jackson's former house cleaner also testified in a separate case, having seen the singer in the shower with Wade Robson when he was less than 10 years old.

The now 30-year-old choreographer has worked with huge artists such as Usher and Pink, and appeared on US TV show So You Think You Can Dance. Wade filed the complaints on May 1 in the case under seal, making them unavailable to the public.

Jackson's family are currently involved in a wrongful death lawsuit filed by Micheal's mother against concert promoter AEG Live.
