Actually its called "Burlesque" as confirmed by Variety, a movie written by the same writer of Erin Brokovich.

As for the plot.... Just take one part Showgirls, one part Glitter and blend together. Pour into a glass and sprinkle just a little bit of Coyote Ugly on top. There you go:

"Aguilera will play an ambitious small town girl with a big voice who finds love, family and success in a Los Angeles neo-burlesque club."

If the rest of the cast is also played by drag queens, then this is going to be a masterpiece that could top Showgirls as the cinematic experience of all time...
