Toni Braxton

At this season's Heart Truth Red Dress show, the celeb-filled fashion show to raise awareness about heart disease, the catwalk strutters skewed a little younger than usual. Gymnasts Gabby Douglas and Nastia Liukin walked (they didn't handspring, sadly), as did Kendall and Kyle Jenner (preceded on the runway by mom Kris), and gorgeous Aussie snowboarder Torah Bright. Minka Kelly and Jamie Chung represented the stunning starlet set, and Soledad O'Brien and Savannah Guthrie brought a little TV journalist gravitas to the proceedings. Kelly Osbourne was on the red carpet, rather than judging it. Toni Braxton and Wendy Williams provided a few goddess moments. Exercise guru Jillian Michaels was there, too, and easily had the best triceps of the whole bunch.

We were saddened to hear today about the passing of Donna Summer, who lost her battle to lung cancer today at the age of 63. Summer moved us (both physically and emotionally) with her strong, sultry vocals, smoldering stage presence, and of course, her unabashedly glamorous look. Not only did her voice define a genre, but her style set the standard for divas to come. You don't have to look far to see traces of Donna's style in some of our most beloved stars today. So, to honor of the late Queen of Disco, here is a tribute to the continued legacy she left on fashion. From Lady Gaga to Toni Braxton, click through to see Donna's style influence.
