Good Morning America anchor Robin Roberts today strolled down a studio catwalk in a red, sequined Isaac Mizrahi dress, but the moment was more about what she wasn't wearing than what she was: She sashayed without her wig. The journo, who strutted her stuff for GMA's "I Dare You" segment, has been battling breast cancer and lost her hair during treatment. Roberts' fellow anchors had dared her to try being a model, but removing the wig was her idea. Doing chemotherapy, she said, was "one of the toughest times in my life. The last thing I felt was beautiful." The dare, she added, "was the perfect opportunity for me to really push outside my comfort zone." - Anna Dimond Related: " Robin Roberts Begins Chemotherapy
