I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Burlesque Movie plot: 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 (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 she 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. One day Ali has to replace Nikki on stage because Nikki is too drunk to perform. Nikki sabotages the performance by turning off the music that the dancers usually lip sync to but before the curtain is dropped down, Ali impresses everyone with her amazing singing skills. Tess immediately decides to have Ali be the star of a whole new show at the club. It becomes increasingly popular and Ali enjoys her newfound stardom while Nikki fumes in the background. Despite the club's growing success, Tess is still unable to pay the bank all the money that she owes it. One night after the club closes, Tess, worried with the club's economic prospects, sings "You Haven't Seen the Last of Me". A very jealous Nikki shows up drunk and picks a fight with Tess, calling Ali a "slut with mutant lungs". Tess, who has grown frustrated with Nikki, questions her gratitude for the help she has received. Angered, Nikki quits on the spot (before falsely claiming that she slept with Vince after his and Tess's honeymoon), and the altercation ends when... My question: Who hired Ali?
