Giuliana Rancic

Fashion Police co-host Giuliana Rancic showed off her new hair color on social media as she prepares to cover this weekend's Academy Award festivities.
"Bye-bye, blonde hair!" Rancic tweeted Thursday.
She also posted a photo of her new look -- as well as info on how she got it -- on Instagram.
"Closer look at my new hair color! For those asking, I used @vidalsassoonproseries #Salonist in Medium Gold Brown (at home kit!) Watch the transformation on YouTube.com/vsproseries #Salonist #ad #hairchange," she posted.
