X17 XCLUSIVE - Mischa Barton Goes Back To Blonde And Sneaks Out Of The Salon

And you know what? We love it! And the colorful sundress is certainly helping quite a bit too...

Mischa Barton showed off her drastically different 'do as she left Byron & Tracey today, and even though there were dozens of photographers camped outside waiting by her brand new blue Cadillac, Mischa snuck out the back so only X17 was able to get shots of the starlet. With the new whip and new 'do, Miss Mischa is certainly going to be getting a lot more attention over the next few weeks!
