Sarah Michelle Gellar is desperate to star in a musical, after being inspired by Renee Zellweger's unlikely transformation into an all-singing, all-dancing star in hit movie Chicago.

Gellar used to believe she would never have the ability to perform a musical role, but after seeing how movie bosses coached Zellweger to singing and dancing perfection, she has confessed her secret aspirations.

She says, "I love the fact producers took a chance with Renee Zellweger in CHICAGO, even though she could not sing or dance. It's great news for me."
