Caitlyn Jenner returned to the spotlight for a night filled with '80s jams. On Friday, the former Olympian surprised the crowd at LA's Greek Theatre to introduce Boy George's performance with Culture Club. Dressed in a form-fitting grey dress and matching leather jacket and thigh-high heel boots, Caitlyn stunned during her brief yet memorable moment on stage. "Thank you very much!" she reportedly said as the audience gave her a standing ovation. "Thank you! Caitlyn Jenner in the house for her first Boy George concert! This is going to be a good group. Thank you so much. E**ugh about me. Thank you for being here tonight. This is so much fun for me and let's hear it here at the Greek Theatre for Boy George!" As the band played their biggest hits, Caitlyn took in the show with friends.
