Sexy former Grey's Anatomy star Kate Walsh raised temperatures on late night TV on Tuesday when she chose to appear on Jimmy Kimmel Live! wearing nothing but a white bath towel and high heels.

The actress told Kimmel she didn't like the fit of her designer gown, and so chose to wear linen instead.

Thrilled host Kimmel asked, "Is today my birthday or something?"

The Private Practice star, who wore the towel during her entire interview on the show, said, "I was supposed to wear a fancy, sparkly sequined dress... It was very hot and I was ready to rock it out. The tailor had taken it in... and I looked like a Vegas stripper. For me, it was not right... I wanted to keep it pure and clean... I'm bringing back the towel."

Walsh showed off the green gown, adding, "Someday I'll wear it."
