Ali (C.A) has such a powerful voice! No can sing "Bound To You" like she can. I also like Maria, Velma, Ariel, and Satine.

Burlesque became one of my fav films. And Christina did great as Ali.

But I haven't seen a lot of these movies.

It's so soothing and simple. She doesn't go over the top, she just sings from the heart.

No one sings like this anymore.

Even if she's since wrecked her voice.
Then Christina Aguilera.

Velma's voice (Catherine's voice) sucks! Great musical ("Chicago") though. I appreciate the fact that Nicole Kidman has such an astounding voice, but she didn't use it to make a music career or something (cheers for you, hahaha! and Whitney: I'm glad it didn't work out for you, I mean, try to make a movie career out of it... hahaha!), and that she doesn't show off of it. She only did for "Moulin Rouge" (I think), but because it's a musical. Judy was born to play in musicals (just like her daughter).

Mariah has the best voice

And Dorthey's

and Rachel (The Bodyguard).
