We do love a good mini-reunion here at Reveal!
Sarah (obvs) played Buffy Summers in the supernatural franchise, while Michelle starred as her little sister Dawn. Seth was werewolf Oz, who dated Buffy's best friend Willow and was part of the Scooby Gang.
Posting the reunion snap to Twitter, Sarah wrote: "I get the best visitors."
We – and plenty of her followers – agree!
More than one thousand people retweeted the image, while over two and a half thousand marked it as a favourite. "Your pictures make me miss Buffy even more," wrote one follower.
Buffy The Vampire Slayer - which revolved around a high school student who was also a vampire slayer - ran for seven series between 1997 and 2003, and spawned the spinoff series Angel, which starred David Boreanaz.
Sarah – who has two children with husband Freddie Prinze Jr – is currently starring in comedy series The Crazy Ones, and it was on the set of the show that Michelle and Seth surprised her.
