Lady Gaga has unveiled a new shaved head look on Twitter.
The eccentric star said the haircut was a tribute to her friend and frequent collaborator Terry Richardson's late mother.
Celebrated photographer Terry, whose subjects have also included Lindsay Lohan and Kate Moss, has captured Gaga behind the scenes and the pair released a coffee table book of images.
Gaga posted the snap of the back of her head on Twitter, together with a caption which references her new track Princess Die, a tribute to the late Princess Diana.
She wrote: "I did it for u Terry. I'm sorry about ure mommy. She has princess die, but we're all princess high."
