Michael Jackson's nephews have revealed that they have launched a $100 million lawsuit against the site Radar Online.

The suit has been penned by the family's attorney Bert Fields and claims that the site has traded for years on false implications about Jackson.

"Radar has tried to profit by launching a vicious and unrelenting attack on Jackson based on claims that, years ago, he was guilty of sexual abuse, even though, at the time, he was found 'not guilty' of that very charge," the allegations read.

"Radar's stories were false and defamatory," their lawyer adds in the lawsuit.

"As a direct and proximate result of the publication of Radar's libelous stories, each of the Jackson nephews has been damaged personally and professionally."
