Mel B alleges in court documents that Belafonte insisted nanny Lorraine Gilles, 26, accompany them on the trip, because he was having sex with the woman.
"I was mortified," the former Spice Girl said. "I would leave the boat daily to go to the gym in an effort to get away."
She also alleges Gilles had an abortion during her affair with Belafonte.
