Stanley Tucci recently did an interview with Cinema Blend, he mentioned & compliment Christina performance in Burlesque.

Is Christina a good actress? What’s her role exactly in the film?

She plays a small town girl who really wants to sing and dance and she comes to L.A. and she finds this burlesque house and ends up working there as a waitress and then, eventually, everyone realizes how talented she is and she kind of saves the day. It’s good. She’s sweet.

Will was just talking about working with Justin Timberlake and his transition from pop star to actor. You just finished Burlesque, right? Christina Aguilera, what was that experience like for you?

It was great, she was wonderful, but she never made a movie before. There were certain things that she just didn’t know, just technical things that she didn’t know. But, you know, you learn them pretty quickly, and God knows she’s a performer. I’ve never seen anything like that. Staggering, her singing and dancing. She’s this sweet little…she’s this big [places flat hand about three feet above the floor]. It was weird. They were like, “There’s Christina Aguilera,” I was like, “Where? That child?” She’s very sweet, very quiet and then she starts to sing and dance and you’re like, “Where the fuck did that come from?” I’ve never seen anything like it. I’ve never seen a transformation like that. It talked about it with Cher. How does she do that? Cher goes, “I don’t know. I don’t know how she does that.”
