Cher and Christina Aguilera Working Together?

Cher in talks to star in Burlesque with Christina Aguilera

Gotta admit Cher and Christina Aguilera starring in a movie together may not be a recipe for huge box-office numbers, but it sure would be a must-see movie. And if certain movie powers that be have their way, it'll happen. I'm totally hearing Cher's currently in talks with the filmmakers behind Aguilera's Burlesque, to see if she might be coming on board, too.

Remember when my bro Marc Malkin first broke the news about this flick (later confirmed by Variety)? Project's about a singer from the boonies who comes to L.A. and performs in a sultry nightclub, one that will quite possibly be run by Sin City vamp expert Cher herself.

But what's most interesting to me is the proposed billing:

"This is a costarring role [being pursued by Cher ]," I'm told by a Cher operator, "not a supporting role."

I can see the battle of the egos already underway, and contracts haven't even been signed yet! I mean, come on, yeah Cher's got a (well-deserved) Oscar and Vegas and boy toys in the palm of her cougar paw. But she hasn't exactly got Aguilera's currency, pipes, heat, limbs or...facial expressions.

Sorry, had to say it. Now, I love my Cher like no other queen around, but let's get real: If I want to see some bitch nightclub owner slap some hard knocks sensibility into little Miss Xtina's film world, it would be nice if that gal could still move her puss. An eyebrow or such. I mean, can't you see Cathy Zeta-Jones just eating Aguilera alive? Who needs the hot-buttered stuff with that kind of treat around?

Of course, I'm getting way ahead of myself here, assuming Cher's not right for the role. Quite possibly, it's her comeback job of the century, right? Maybe Cher's perf for this part and I'm just jealous of the gal's fab wig collection?

Readers, what say you?
