Aguilera was apprehensive of big screen debut

Los Angeles: Singer-turned-actress Chritsina Aguilera has revealed she was wary of agreeing to her debut movie role in `Burlesque` because she heard so many "horror stories" about pop stars making unsuccessful crossovers to the big screen.

The "Dirrty" hitmaker stars alongside Cher and Kristen Bell in the new film, playing a wannabe dancer struggling to make it in Los Angeles and Aguilera admits she has wanted to act for a long time, but was put off by seeing her pop star peers including Britney Spears in "Crossroads" and Mariah Carey in "Glitter" flop at the box office, reports

"You`ve heard a lot of horror stories. And a lot of people don`t make successful crossovers. That`s why I think I also just really took my time in choosing the right thing and not just saying, `Hey, let me try this just to do it and say I did it`. If you don`t, I think the work would suffer and then you`d get written off as just another one trying to do something they can`t do," she said.
