Tori SpellingTori SpellingWhat is it with Chicago?

More than any other show, there seems to be a never ending supply of celebs waiting to sing and dance their hearts out in the famous musical.

The latest big names preparing to step into the dancing shoes of the leading characters are Tori Spelling and R 'n' B star Usher.

Yes, we said Tori Spelling and Usher.

Now, don't get too excited, we're not talking London's West End, we're talking about treading the boards of New York's Broadway.

Usher has already signed on the sparkly line to play slick lawyer Billy Flynn - which we think will definitely be worth seeing.

And Tori is in talks with producers to play Roxie Hart.

G Usher 01/05UsherWe're not sure that we've heard Tori sing or dance before, so we're very curious.

Other stars who have appeared in the musical include Brooke Shields, Melanie Griffith, Huey Lewis and Billy Zane.

If Tori takes the part, she'll be on stage and giving it her all from August.

We hope she can cope with all that jazz.
