Los Angeles, Aug 13 (IANS): A woman who used to work as a nanny at Mel B's house has filed a lawsuit against the star claiming that the singer acted as "cameraman" to film alleged threesomes with her estranged husband Stephen Belafonte.

Mel B had earlier alleged that nanny Lorraine Gilles had an affair with Belafonte and aborted his baby. Subsequently, Gilles filed a 128-page lawsuit against the star in which she hit back at the 42-year-old pop singer's accusation, reports dailymail.co.uk.

In documents filed in California's Superior Court on Friday, Gilles, 26, claimed she had sex "multiple times a week" with Mel B over a seven-year period and only slept with Belfonte on the singer's "instruction".

"My sexual and employment relationship with Melanie continued for approximately seven years until September 2016. During my time with Melanie, she and I had sex sporadically, sometimes having sex multiple times in a week," she said.

"On the other hand I never had any sexual relations with Stephen without Melanie's instruction and without Melanie's actual or apparent consent. At no point did I represent to Melanie that I was pregnant with Stephen's child.

"The only times Stephen and I had sex was when Melanie instructed Stephen and I to do so. Or when Melanie herself invited her husband to join us in the bedroom, at which point Melanie would often serve as the 'cameraman' and record the sexual encounter or take part in the menage a trois herself," she added.
