If you’re old enough to remember when Buffy stopped slaying vampires to play the Marsha [bleeping] Brady of the Upper East Side in “Cruel Intentions,” then we might have some of the best news you’ll hear all day. Three of the film’s stars — Reese Witherspoon, Selma Blair and Sarah Michelle Gellar — reunited; and it feels so good seeing them together again.

The actresses were spotted at a performance of “Cruel Intentions: The Musical” in Los Angeles on May 28. (Are you remembering the parody song in the movie “Not Another Teen Movie” where the character based on Gellar’s in “Cruel Intentions” bursts out with, “So what if we have the same mother. Tonight I’m gonna f-ck my brother”? We’re guessing it was nothing like that.)

Witherspoon, Blair and Gellar posted plenty of pics to their Instagram accounts during their night out together.

Oh, and that kissing scene was totally reenacted by Blair and Gellar. After swapping saliva a sweet 16 years later, Gellar posted on Instagram: “My lessons paid off!”
