Ashlee Simpson-Wentz Forgets Chicago Co-star

Ashlee Simpson-Wentz was left red-faced on live U.S. TV on Thursday - after forgetting the name of her leading man in Broadway musical Chicago.

The singer-turned-actress made her Broadway debut as Roxie Hart on 30 November.

And, after almost a month of performances, Simpson-Wentz was tongue-tied when asked to recall her co-star Brent Barrett, the actor who plays Billy Flynn, during a segment on breakfast programme, The Today Show.

Embarrassed, the star appeared desperate to remember the name, but instead excused herself: "Oh my god! Names, names, names, names, names."

The 25 year old has already tested her popularity backstage - castmembers reportedly complained she barricaded her family from the rest of the cast in "a makeshift Vip section", at an after-party for her debut.
