Sisters forever! Sarah Michelle Gellar wished her former Buffy the Vampire Slayer costar Michelle Trachtenberg a happy 30th birthday on Sunday, Oct. 11, with a sweet photo montage that’s totally made our day!
“How is it possible that you are #30 @michelletrachtenberg I met you as a little girl on #allmychildren and have continued to watch you grow,” the Cruel Intentions actress captioned an Instagram photo. “You may be taller than me now, but you will always be my little sister. You have the #key to my heart #btvs #gossipgirl #michelletrachtenberg #happybirthday.”
The pair met on All My Children in the mid-’90s, and Trachtenberg later played Gellar’s sister, Dawn, on Buffy the Vampire Slayer for three years until 2003.
The photo, consisting of four small pics, shows the two actresses together in three of the pics, along with a solo shot of the Gossip Girl actress. In the caption Gellar also made a Buffy reference that fans of the show will remember — “You have the #key to my heart,” Gellar wrote, referring to Trachtenberg’s character being the mystical Key.
Gellar, 38, and Trachtenberg also reunited last September at a private screening of the 2014 film Annie, along with their former Buffy costar Seth Green.
