No doubt causing serious happiness to Buffy fanatics across the world, the former co-stars posed together in aid of the animal welfare It's Cool To Kind organisation.
Sarah tweeted alongside the snap: "Best surprise visit ever! It's #CoolToBeKind. Thanks for the bracelets."
The blonde star played the vampire slaying, demon butt-kicking Buffy in the sci-fi series, with Anthony featuring as her watcher and father-figure Giles.
Buffy fans were thrilled (to say the least) about her picture, with comments including, "This may be THE photo of 2014" and "Omg, this makes my heart so happy!"
A third said: "Aww, great to see you both together! Brings back some of my favourite TV moments." Another added: "Love you guys! I hope Buffy gets to be reunited with Giles in a movie sometime soon in the future."
Cool To Be Kind was co-founded by Anthony to help promote, encourage and acknowledge acts of kindness to animals.
We loved him in Buffy and now we love him even more!
