Aguilera’s Ali runs away from Iowa in search of fame and ends up waitressing at The Burlesque Lounge on the Sunset Strip. That is until Kristen Bell’s headliner, Nikki, shows up tipsy one night and Ali must fill in.  Ali helps turn what once was a lip-sync club into a singing-and-dancing revue after she displays her vocal fireworks onstage in numbers like “But I’m a Good Girl.”  Cher is Tess, owner of a retro club who has a modern-day problem: She can’t make the payments on her over-mortgaged property.  Together, Ali and Tess manage to transform the Burlesque Lounge into a success.  Stanley Tucci is Sean, the lounge’s stage manager, a go-to guy for the gals and best friend to Tess.   Every night, Tess and Sean put together the costumes for that evening’s performance. Other men in the cast include Cam Gigandet (Twilight) as Jack, Ali’s piano-playing love interest; Eric Dane as entrepreneur Marcus, who tries to woo Ali away; and Alan Cumming as Alexis, the gender-bending doorman.
