British pop singer Jessie J ("Price Tag," "Domino") recently pulled a G.I. Jane/Sinead O'Connor/Natalie Portman.

Back in 2011, Jessie said she'd shave her head for charity, going through with the plan on March 15 to support Comic Relief's Red Nose Day. She shared this photo on Instagram, writing, "I did it! Thank you to everyone who is donating! Please keep texting YES to 70010 x #headshave #comicrelief."

At the time, Jessie said of her new hair, "It's the weirdest feeling," but she also called the drastic cut "liberating."

It also renders her pretty unrecognizable, not that she was super-famous in the U.S. by sight, but we'd gotten used to her Cleopatra cut.

What do you think? She actually has a gorgeous head shape, which you don't really know until the hair is gone. And this really makes her features stand out.

Should she keep the shaved head or slowly grow it out?
