Mary-Kate Olsen Does the Sun Dance

Mary-Kate Olsen arrives at the premiere of The Wackness on Friday held at the Racquet Club Theatre during the 2008 Sundance Film Festival in Park City, Utah.

MK told the audience that filming her makeout session with costar Ben Kingsley was ”fun” – even though she was worried the whole time about accidentally removing his hairpiece.

That might make things slightly awkward!
