Britney Spears

Britney Spears' "comeback" performance at the MTV VMAs in 2007 was much talked about for two reasons. 1) She was, in a world, awful, and 2) her abdominal muscles had been painted to look more toned with spray tanner. Mind you, it's absurd to expect a mother of two to have the same six-pack as she did when she was 16; however, it would take Da Vinci coming back from the dead and wielding the tanning spray gun to make paint look like real muscle.
