"What I think is hot is confidence…and is being in front of the eyes that matter to you most," said glamour model and reality television personality Kendra Wilkinson. "I think 'hot' is being confident." With her husband's support being what matters most to her, she added, "At the end of the day that is all that matters--is what I wear in the bedroom."

"It's cliche and you hear it all the time but it's so true--its confidence," said Melissa Rycroft, former Dallas Cowboys cheerleader. "I don't think you have to be the most physically attractive person but if you own it and you exude confidence, I think that just makes you uber hot and sexy."

On a heavier note, Rycroft, who is a contributor to Good Morning America and was once a co-host of Dick Clark's New Year's Rockin' Eve, talked about the sad passing of Dick Clark this week. She recounted a story in which Clark said that he was a big fan of hers and wrote her a letter that she still has.
