But there was still plenty of skin on show - the full length dress was slashed to the thigh and featured a plunging neckline.
Earlier in the day, Kelly went to the gym with her personal trainer for a workout to ensure she was in the best shape possible for the red carpet do at Grauman's Chinese Theatre.

She also shares a lesbian kiss underwater with porn actress Riley Steele.
Speaking at the Breakthrough of the Year Awards in Los Angeles, she said: 'Having this movie coming out where I get to make out underwater with a porn star naked, I just thought "why not just embrace it and make this month my naked month where everything I do is naked?".'
She actually was criticised for appearing in a bikini in nearly all of her scenes.

But she said she was happy to show off her figure in the film as she knows her curvy shape will not last.
She added: 'If people want to cast me in roles for my body or how I look, I’m just doing to embrace that because that’s not going to be the case forever.
'It doesn’t make me any less important than anyone else in the movie just because I’m in a bikini. That’s just the role I play. It’s as much a part of the story as the piranhas and everything else.'
