Looks like Nelly and Ashanti may be back together.  Ashanti with her full family in tow were on hand for Nelly's 5th Annual Black and White Ball.

The charity event, now in its fifth year, was held at the Chase Park Plaza's Khorassan Ballroom.

Ashanti hit the stage to perform some of her hits including 'Happy' and 'The Way That I Love You,' before pulling her beau up for a serenade of 'If I Was Your Girlfriend.' The two later re-teamed for 'Body on Me, which was featured on both of their fourth albums, Ashanti's 'The Declaration' and Nelly's 'Brass Knuckles.'

Residents of Saint Louis turned out in droves to support the organization which also awards scholarships to students attending nearby Lindenwood University. The 2011/2010 Black and White Ball Scholarships will provide recipients with full scholarships covering all four years of their education.

Nelly's parents and a host of other celebs were also on hand to support the event.
