British singer Jessie J drastically chopped her hair over the weekend - and by drastically, we mean she shaved her head!
It's all for a good cause, though: The "Domino" singer shaved off her trademark raven locks to raise money for the 25th annual Comic Relief fundraiser.
"I did it! Thank you to everyone who is donating!" she tweeted after the event.
The fundraiser - flanked by additional celebrity support from One Direction, Simon Cowell and others - eventually raised about 75 million British pounds (about $113 million U.S. dollars).
She isn't the only female celeb to cut off her famous locks: A bunch of celebs have for various different reasons.
Former "American Idol" finalist Kellie Pickler is as well known for her blonde strands as she is for her big pipes. That didn't stop the current "Dancing With the Stars" contestant from shaving her head in September 2012.
The reason? She wanted to support her best friend, Summer Holt Miller, in her fight against breast cancer.
"Cancer does not discriminate," Pickler wrote on Facebook of the reasoning behind her decision. "Today was one of the most incredible days of my life."
No one is really quite sure why Britney Spears shaved her head in February 2007, but that didn't keep people from speculating what her reasons were. Her so-called "manager" at the time, Sam Lufti, said Spears was trying to cover up her meth use.
"She liked to use amphetamines, speed or uppers . . . and most of the things that went wrong were related to that drug," Lufti said in October 2012 during his libel suit against Spears' parents, Lynn and Jamie Spears.
The lawsuit was eventually dismissed, likely because Lufti is not a reliable source.
What we do know? Britney is looking much better these days.
South African beauty Charlize Theron shaved her trademark blond strands in 2012 for her role in "Mad Max: Fury Road."
She still looked gorgeous, of course - and it's safe to say she loves the results.
"I highly recommend it. I think every woman should do it," she told Ryan Seacrest at the 2013 Academy Awards. "I had two huge garbage bags full of hair products. It's so freeing."
Robin Roberts made her triumphant return to "Good Morning America" in late March - complete with a shaved head. But, it wasn't for vanity: The popular journalist went through a bone marrow transplant to cure her Myelodysplastic Syndrome (MDS), a rare blood condition.
"My doctors tell me I'm going to beat this - and I know it's true," she said after her diagnosis.
And she has!
