Aspiring thesp Kelly Osbourne is putting her movie career on hold. The Osbournes star has dropped out of Disney's upcoming Freaky Friday remake due to personal reasons, according to The Hollywood Reporter. The flick — which stars Annette Bening and Lindsay Lohan — would have marked Osbourne's big-screen debut. Her mom, Sharon Osbourne, currently is undergoing treatment for colon cancer — but it's unclear if that was a factor in her decision. Actress Christina Vidal will replace her in the best friend role.
