Better off blonde?

Aubrey O'Day was kicked off Celebrity Apprentice on Sunday, so naturally she celebrated by getting a makeover.

"OMG my blonde hair is BACK BITCHES! I finally feel like myself again! Auberellllllaaaaa!" she tweeted after sharing the pic above of her new look.

The singer, who ditched her blonde locks for a bright, fiery red color back in September, gave a shout out to the colorist who did the new hue: "Love you Jo at Dop Dop Salon in NYC for making me a blondie again so effortlessly! Everyone go get colored by her!"

The 28-year-old Danity Kane alum was the last star fired before the top two contestants -- Clay Aiken and Arsenio Hall -- advanced to the final challenge, which airs May 20. O'Day was known for butting heads with Hall, and their feuding began to get heated towards the end of her run on the show.

"[Arsenio] doesn't want strong women to have too much of a voice. Typical in this industry," she told Us Weekly in April.
