Olivia Wilde: Blonde & Beautiful on "LIVE! with Kelly"

Showing off her fresh new look, Olivia Wilde ventured out in New York City on Wednesday (April 18) for an appearance on ABC's morning talk show "LIVE! with Kelly".

As she walked onstage, the "House" hottie quickly drew a comment about her changed appearance from Miss Ripa, who said, "You are a stunning blonde!"

To this, Miss Wilde - who told that she was blonde for years before going brunette - happily replied, "And it is so much more fun!"

The 28-year-old continued to explain the motivation behind her lighter locks, saying, "I did it for a movie. I did it for this Ron Howard movie I just finished called 'Rush' which is set in the '70s."

"It's all about Formula One racing. It was so cool. So, [co-star] Chris Hemsworth and I are both the same shade of blonde. Same haircut, too," Olivia added, with the full interview available to be viewed below.
