Lady Gaga isn't one to care much about changing up her look in a drastic way; she's got a posse of stylists and designers at her beck and call who can change it back when she gets tired of it, and besides, it's part of her charm.
Gaga recently debuted a new partially-shaved head and posted a photo of the new haircut on Twitter, explaining that it was in honor of the passing of a dear friend's mother.
I did it for u Terry. I'm sorry about ure mommy. She has princess die, but were all princess high http://t.co/HY4Bpltl
"Terry" refers to Terry Richardson, a high-profile photographer and good friend of Gaga's who lost his mother recently. Though it's not exactly clear what having a shorn head has to do with honoring the dead, it's clear Gaga meant it as a show of respect to Richardson, as was the Twitter quote which comes from one of her latest songs.
