Cher to Play Catwoman in New Batman Movie?

Is Cher on tap to play Catwoman in the latest Batman movie? The Telegraph says oui:

A studio executive said: "Cher is Nolan's first choice to play Catwoman. He wants to her to portray her like a vamp in her twilight years.

"The new Catwoman will be the absolute opposite of Michelle Pfeiffer and Halle Berry's purring creations."

I'm taking this with a big grain of salt, but given the trajectory of the films so far, such a storyline featuring an aging Catwoman is not completely out of the real of possibility.

Cue the fan posters and the Photoshop.
