Sarah Michelle Gellar reunites with Cruel Intentions co-stars on her birthday

She met up with her fellow actors from the 1999 film, Ryan Phillippe and Selma Blair

Sarah Michelle Gellar has celebrated her birthdayby reuniting with herCruel Intentions co-stars Ryan Phillippe and Selma Blair.

The Buffy the Vampire Slayer actor, who played scheming Kathryn Merteuil in the 1999 teen drama, marked turning 45 by reuniting with her fellow stars.

The film, inspired by the 1782 French novel Les Liaisons Dangereuses, and subsequent film Dangerous Liaisons, moved the story to the world of wealthy high school teenagers in New York City.

Gellar played the queen bee of an upscale New York school, while Phillippe played her stepbrother Sebastian Valmont, with whom she schemes to seduce virginal ingenue Cecile Caldwell, played by Blair.

The pair also bet over whether Valmont can seduce the new principal’s daughter, Annette Hargrove, played by Reese Witherspoon.

Gellar shared a string of photos of the trio together in front of art from the film hanging in a Los Angeles art gallery.

One picture in artist Sam McKinniss’s exhibit at Jeffrey Deitch Gallery in Los Angeles shows Gellar and Blair in the famous scene in which the pair share a kiss, while another shows a nude Phillippe from behind as he towels off next to a swimming pool.

Gellar captioned the photos: “Art and surprises on my birthday. What a special day.”

The trio were also joined by the film’s director, Roger Kumble, and producer Neal Moritz for the gallery trip.

Blair was accompanied by a support dog she was given after being diagnosed with MS.
