Osbourne worries about West End role

Kelly Osbourne has admitted that she is feeling nervous about making her West End debut.

The singer and reality TV star has signed up to play Mama Morton in hit musical Chicago, but she fears that her lack of theatre experience could be a problem.

"I'm absolutely bricking it because the only theatre I have ever done before this was my school play - and I was a windmill!" Kelly told The Sun.

She added: "The biggest problem I have is everyone who has seen the film now thinks Mama Morton is a big black woman because Queen Latifah played her."

Osbourne's first performance will be on September 10.
