Photo Coverage: Ashlee Simpson Joins Chicago in London

Ashlee Simpson--joined by sister Jessica Simpson and others--celebrated the cast change of the London production of Chicago at the show's September 25th after-party.  Simpson assumed the role of Roxie Hart that evening, and will stay with the hit musical for a limited six-week engagement.

The 21 year-old singer's albums include "Autobiography" and "I Am Me."  The singer, who is the sister of pop star Jessica Simpson and who also appeared on an eponymous reality show, has also appeared on film in Undiscovered and The Hot Chick, and on TV in "7th Heaven" and "Malcolm in the Middle." 

London's Chicago, currently playing the Cambridge Theatre, is now in its 9th year.

The Broadway production of Chicago, which opened at the Richard Rodgers Theatre on November 14th 1996, has reached a run of over 4,000 performances at the Ambassador Theatre (215 W. 49th St.); the show will celebrate its 10 year anniversary in November. Chicago received 6 1997 Tonys (including Best Revival of a Musical) under the direction of Walter Bobbie and the choreography of star Ann Reinking. The revival, based on Bobbie's stylistically stripped-down Encores! staging, featured direction and choreography by Bob Fosse in its original 1975 production. Chicago features a score by John Kander and Fred Ebb, and a book by Ebb and Bob Fosse.
