Lorraine Gilles has filed a lawsuit against the former Spice Girls singer after she was involved in declarations made by the star surrounding her divorce from estranged husband Stephen Belafonte.

Mel claimed that Stephen had been having an affair with Lorraine, whom the 41-year-old singer claims was pregnant with Stephen's baby prior to having an abortion.

The 'Wannabe' hitmaker also goes on to accuse Lorraine and Stephen of "pilfering money" from her, and in another declaration claimed that the nanny had control over the star's personal sex tapes which she feared Lorraine could spread.

Lorraine has now reportedly branded these statements as false, and is suing the brunette beauty for defamation, according to TMZ.com.

TMZ also reports that whilst a person "can't usually be sued" for the information they provide in court papers, California family law cases make an exception when someone makes a claim against a third party, which in this case is Lorraine.

Earlier this month, the publication also reported that Mel had been granted the restraining order she filed against the ex-child care worker, which banned Lorraine from annoying, harassing, molesting and coming within 100 yards" of her.

The pop star's lawyer also got permission from the courts to gain access to a storage locker rented by Lorraine because Mel was convinced her former employee was stashing sex tapes and raunchy photos of her that she and Stephen had allegedly threatened to leak in a bid to destroy the brunette beauty's life.

The documents said the locker contained boxes and boxes of Spice Girls memorabilia and photos of her recently deceased father Martin Brown.

However, when Mel, her lawyers and the police turned up at the locker facility, they found nothing - despite the judge ruling that Lorraine must not remove anything.

The 'America's Got Talent' judge was also awarded a restraining order against her husband - with whom she has five-year-old daughter Madison - earlier this month, after she accused him of abusing her, getting their nanny pregnant and forcing her to take part in threesomes.

She alleged the abuse started within the first year of their marriage in 2007 and became a "pattern" for the then-couple with Stephen allegedly choosing to "beat her down to let her know he was in charge" whenever she saw a spike in her career.
