It seems like a new celeb reveals a drastic new haircut every day, and tonight is all aboutLady Gaga. But this singer didn’t do it just for the thrill or to jazz up her usual ‘do, she did it for a friend.

“I did it for u Terry,” she tweeted, linking to her blog. “I’m sorry about ure mommy. She has princess die, but were all princess high.”

The photo shows the back of (at least what we think is) Gaga’s head, with her hair pulled up into a high bun, revealing a triangular section of her hair shaven off. 

The “Terry” Mama Monster is referring to is famous photographer and friend Terry Richardson, who posted on his Tumblr page today, “R.I.P. Annie Lomax, My Mom 1938-2012”

In 2011, he released a book titled, Lady Gaga X Terry Richardson, which shows all of his photographs of the singer.
