Sarah Michelle Gellar is having "the most fun" on vacation!

The Buffy the Vampire Slayer alum, 44, shared a few snaps from her girls' getaway at the Esperanza Resort in Los Cabos, Mexico on Friday, looking fresh-faced, glowing, and totally relaxed.

"Weekend me is more fun… weekend me away from home… the most fun," she wrote alongside two selfies, the first in which she's rocking a teeny, tiny one-shoulder black bikini and gold-rimmed aviator sunglasses, ready for another day of soaking up the sun.

Earlier this month, Gellar celebrated husband Freddie Prinze Jr.'s 46th birthday – which falls on International Women's Day – with a sweet tribute on Instagram.

"It completely makes sense that you share that day, as there is no man that is a bigger champion and friend to women than you," she wrote. "I couldn't think of someone better to raise a daughter with or to teach a son, what it truly means to be a good man. Happy birthday FP."

Gellar and Prinze met while filming the 1997 horror hit I Know What You Did Last Summer, and wed in 2002. They share two children: son Rocky, 9, and daughter Charlotte, 12.
