Kelly was also working the red carpet as a Fashion Police critic for E!, a job that proved to be quite difficult. Kelly said, “It’s amazing to me that there are just as many good dresses as sh*t ones how the hell am I going to pick best/worst.” Well, Kelly probably did not make any of those lists, but she looked fantastic.
