“This is #CharlynWillis,” Gellar wrote. “She got engaged yesterday, and meant to text her sister, but in all the excitement, got me instead. Her sister didn’t respond, but I did. So please help me say congrats, to Charlyn. (And her fiancé whose name I don’t know) #congratulations.”

While Gellar’s response is pure gold, Willis’s response to the attention might be even better.

“Omg! Thank you Sarah!” Willis wrote in a comment on Gellar’s Facebook page. “His name is Dennis! Thank you so much for this. You’ve truly made my engagement experience even more of a life changer! Please know when we set a date, I’ll be reaching out to invite you, Freddie, and the kids!”

Looks like Buffy the Vampire Slayer might have unintentionally scored a wedding invite.
