Kelis hosted "Marquee Mondays" Marquee Nightclub in Las Vegas on Monday looking like a hot mess. She mixed leopard-print tights with a sheer, cleavage revealing shirt and a biker jacket.

Last month the singer was slapped with a lawsuit from the bosses of a talent agency amid allegations she failed to pay for services used last year.

The Milkshake singer and her management hired staff at Drive Talent Inc. to provide "goods and services" for a variety of performances on TV shows, including appearances on Today, The Tonight Show with Jay Leno, and Late Night with Jimmy Fallon.
