"Bigger Than Britney" Show Will Slim Down Star Lookalikes

An upcoming U.K. show called "Bigger Than Britney" will feature overweight celebrity lookalikes vying to lose weight using their famous doppelganger's signature diet and training regimen. An overweight Britney Spears lookalike, for example, might follow the strict diet and daily gym sessions -- which Spears notoriously punctuated with 500 abdominal exercises daily -- following her 2006 divorce.

Sky Living HD is currently still casting for "Bigger Than Britney." Producers are looking for women aged 20 to 35 who wear a size 14 to 18 and look like Beyonce, Lady Gaga, Cheryl Cole, Katy Perry or Rihanna.
