About me: Ali Rose (Aguilera) moves to Los Angeles after she quits her bar job when her boss refuses to pay her. Once in L.A., she tries and fails at every audition she does until one night, she finds herself unknowingly in a burlesque club when she hears the music on the street. She finds Tess (played by Cher) and the dancers performing “Welcome to Burlesque” and decides to pursue a career on stage once she meets Jack (Gigandet). Jack refers her to Tess for an audition, but is rejected instantly and ushered out by Sean (Tucci). Instead of leaving, Ali begins serving customers at the club as a waitress, while Tess and Sean observe with Jack asking Tess to give Ali a chance.
When Georgia (Hough) becomes pregnant, auditions are held to replace her. Ali begins her audition when everyone leaves, and after performing "Wagon Wheel Watusi", persuades Tess to allow her to become one of the club's dancers, much to the annoyance of Nikki (Bell), a performer who is always late and caught drinking before numbers. Despite the club's growing success, Tess is still unable to pay the bank.
Tensions arise between Ali and Jack as Marcus grows increasingly infatuated with Ali, making Jack jealous. At Georgia's wedding, Jack appears to call off his engagement, getting drunk. That night, Ali and Jack sleep together, but the following morning Jack's fiancé, Natalie (Agron), returns unexpectedly from her play in New York and tells Ali that the engagement is still on. Jack denies this, and while trying to fix things, he asks Ali to leave. Feeling heartbroken and betrayed, Ali runs to Sean for support, who prompts her to go with Marcus after his phone call.
While spending time with Marcus, Ali finds out about "air rights", which refers to the empty space above a building and what can be done with it. Ali breaks things off with Marcus after she sees his plans to build a skyscraper on the property the club is on. Ali tells Tess, and together they inform the owner of the new million-dollar condos across the street; fearing the loss of business that would result from the obstruction of his prospective tenants' view, he purchases the air rights to the club's property. The resulting money is enough for Tess to buy out Vince's share, pay off the bank, and re-fashion the club to her own vision. She also makes up with Nikki and rehires her at the club. In the end Ali, having reunited with Jack and earned Nikki's respect, performs "Show Me How You Burlesque" with all of the dancers, a song which Jack wrote and finally finished.
But things didn't work out with jack now she hopes to find a true love that isn't a lie.
