Keira Knightley suffered a style blunder at the London premiere of her new movie A Dangerous Method on Tuesday night (31Jan12) after stepping out with patchy fake tan on her back.
The actress donned a floor-length Burberry dress for the star-studded screening, and the burgundy gown featured a triangular cut-out panel below her shoulder blades.
But the revealing design showed off Knightley's two-tone back, seemingly the effect of uneven application of fake tan.
However, she didn't let the dress disaster ruin her night - she was snapped dancing wildly with her movie co-star Michael Fassbender at the afterparty, and the notoriously-private actress openly kissed her boyfriend, The Klaxons rocker James Righton, in the back of a taxi as they left the bash.
