Kim Kardashian is hitting the bottle again.
The buxom peroxide blonde says she's going back to her natural brunette locks now that the summer is over.
"I'm dying [sic] my hair back dark," she wrote on her blog. "Bye bye blonde, see u next summer!"
The shapely reality show stunner spent about a month as a blonde after first debuting the lighter look on the red carpet at the Teen Choice Awards in Universal City, Calif., on Aug. 9.
"I'm really a blonde this time!!!" she wrote on her Twitter page. "Stepping out on the red carpet as a blonde!! Ahh!"
The "Keeping Up With the Kardashians" star claimed she had a blonde do in April when she posted photos of her as a blonde on the Web - but she later confessed she was wearing a wig.
Kardashian recently split from her boyfriend, NFL player Reggie Bush.
