In her lawsuit, she described how on the night of October 6, she was working at the nightclub where she is a hostess when Nelly was performing.
After the alleged attack, she said was thrown off the bus by a member of Nelly's entourage.
Kelly also relaunched her YouTube channel this year, where she breaks down her gym workouts into sessions focusing on upper body, abs, legs and booty 'I eat lots of fish, all vegetables except potatoes, I love slow-release carbs like oatmeal for breakfast, yogurt and lots of berries and fruits,' Kelly added.
Earlier this month, photographs of Nelly standing handcuffed after being arrested for the October 7, 2017 rape were released.
