Ashley Roberts came bottom of the leaderboard on Saturday's BBC The Wheel. 

The American singer, 40, appeared on the hit BBC show after being drafted in to help the contestants answer trivia questions from her area of expertise for a chance at winning the cash prize. 

The former Pussycat dolls member joined some of showbiz's big names including Peter Andre, Rob Beckett, Patricia Bright, Richard Coles, John Barnes and Lucy Worsley.

Roberts chose the United States of America as her expert category during her appearance on the show.
