"Girls" star Jemima Kirke shared a video of herself chopping off her hair.

While topless.

"Long hair. Don't care," Kirke wrote Wednesday on Twitter. "Going for the mom-who-had-a-tough-year-who-doesn't-feel-like-brushing-her-f---ing-hair look."

The British-born beauty's hair used to reach her hips, but she cut her blonde locks just past her shoulder. 

She plays Zosia Mamet's character's cousin Jessa Johansson on the HBO show.

Kirke has two children with lawyer husband Michael Mosberg. They welcomed daughter Rafaella Israel in 2010, and son Memphis Kirke in 2012.
