The singer Christina Aguilera thinks that she might have put on too much of weight over the weekend at the Los Angeles County Museum of Art. Burlesque played by Cher, Christina plays the role of a little town girl who ventures to Los Angeles and finds herself in a neo-burlesque club. However, her weight gain has left many insiders mystified. Many believes that she has put on about a stone in the past three months. “The whole movie is choreography and she was very active so I’m surprised she’s piled on the pounds so quickly.” Anguilera says.
