It's time for a celebrity tag team! R&B singer Christina Milian will join former "Saved By The Bell" star Mario Lopez (Slater) in a new TV sitcom, informs Starpulse. Mario, who recently appeared on the talent show "Dancing With The Stars," will star as a slick New York executive in the pilot of Eight Days A Week. Milian is set to play a gorgeous ex-law. Now there's a stretch. Please, will it even be acting for her?
