Lady GaGa has gone brunette.

The 26-year-old singer shocked the world by debuting her demure new image yesterday (20.08.12), revealing on twitter her new shade of ''Louis Vuitton brown''.

Gaga posted a series of tweets with pictures of her new chestnut-colored locks and explained why she had made the decision to ditch her trademark blonde locks.

Writing on twitter, she told her fans: ''I'm gonna leave one streak of bad by my left ear. Lady when its down, and Gaga when its up. could we belong together?

''Definitely feeling less blond lately and little more progressive brunette. I am LOUIS VUITTON BROWN. B**** THATS LV. (sic)''

She later added: ''i think I'm gonna do away with this blond streak, feeling like a purist. gosh i forgot what it was like to have soft hair!''

The controversial singer is famed for her ever-changing look and collection of wigs, rocking blonde, orange, grey and Pink hair in the last year alone.

But it seems the pop superstar - real name Stefani Germanotta - is keen to tone down her image of late and has gone back to her Roots with a more natural look.

The 'Judas' singer said at the start of her career that she dyed her hair platinum blonde as a tribute to her musical icons Britney Spears, Madonna and Marilyn Monroe, as well as to avoid being mistaken for the late Amy Winehouse.

Gaga showcased her new hairdo for the first time in public when she landed in Vilnius, Lithuania, as part of her 'Born This Way' European tour.
