Monica arrived at the 2012 Billboard Music Awards, which was held on Sunday night (May 20) in Las Vegas, Nevada.

She picked out a white long sleeve gown with a revealing keyhole, an embellishment detailing in the center of the waist, and a thigh-high side slit by Roberto Cavalli.

Her fitted gown was matched with sparkly diamond stud earrings, a metallic gold and multi-colored clutch by Roberto Cavalli, and animal Christian Louboutin "Daffodile" platform pumps.

A braided updo and a glossy light purple lip shade rounded out her great look.
