The actress took to Instagram on Friday and showed off her brand new brunette 'do, as she preps for the TV reboot of "Cruel Intentions."
"#brownhairdontcare (actually kind of love it!!) thank you everyone @andylecomptesalon," she captioned the pic.
In the photo, the formerly-blonde star shows off her new dark tresses while flashing a big grin. While the mom-of-two didn't give a reason for her hair switch up, she recently signed on to reprise her role as the villainous (and brunette) Kathryn Mertruil in the upcoming NBC series.

The 38-year-old "Buffy" alum rocked raven locks for the 1999 film and also shared a photo of the pilot's script on the 17th anniversary of the film's release. "How I am spending the 17 anniversary of the release of #cruelintentions #Crueltv," she said of the pic.
Gellar announced she'll return for the series on Instagram last week, with a Then & Now photo and the caption, "That's right 'everybody loves me, and I intend to keep it that way' #kathrynmerteuil is back!!! I am happy to say that I will be joining them (and @nbctv ) on the new #Crueltv."
