Singer Mel B has asked a judge to seal her divorce and restraining order cases as she fears her estranged husband Stephen Belafonte will play their sex tapes in public.

According to new documents filed by the singer, and obtained by tmz.com, Belafonte intends to enter 54 videos as exhibits in their legal battle.

Mel B says Belafonte has made it clear he intends to disclose sensitive information and videos in court.

She has admitted that at least one of the videos "includes sexually explicit" images of her and Stephen, reports tmz.com.

Mel B believes that the court has a duty to shield her children from being exposed to the sex tapes and any other explicit material he intends to air in court.

In the documents, she says the best way to do that is to seal the case, and close the courtroom when her restraining order case against Belafonte goes to trial.

Mel B has three children -- Phoenix Chi, whose father is her first husband Jimmy Gulzar, 10-year-old Angel Iris, who was fathered by her former lover Eddie Murphy. She also has a daughter Madison with Belafonte.

Their marriage fell apart after Mel B filed for divorce amid claims her husband had been sleeping with the family nanny Lorraine Gillies behind her back.
