The reality star known for her deep brunette locks went blonde over the weekend and showed off lighter locks as she walked the red carpet at the 2009 Teen Choice Awards held at Gibson Amphitheatre on August 9, 2009 in Universal City, California.

Last week, Allure magazine introduced a new word into the lexicon: the break-over. Apparently this term describes the new look a woman sports shortly after a breakup. Perhaps it was Kim Kardashian’s recent breakup with NFL star Reggie Bush that inspired her to dye her hair a soft, slightly-brassy blonde. Kim, who wore a blonde wig for a recent photoshoot, took to her blog to write about the new do:

“This time it’s for real, guys! I went blonde!!! I had been considering it ever since I wore that blonde wig, and I just decided to go for it!! What do you think? I am really loving it! My hairstylist Clyde Haygood orchestrated the whole thing and Rebecca from Goodform salon dyed it!”

No one has perfected better the sultry brunette image than Kim, obviously she still looks gorgeous, but if you think about it she completely looses her personality with the new hair color. She will eventually return to her roots..
