Sarah Michelle Gellar no doubt made her fans do a double-take when she shared an unrecognizable photo of herself on Thursday.
The Buffy the Vampire Slayer star took to her Instagram Stories to share a frightening photo that saw her face and chest covered in what appeared to be gray ash while wearing nothing but a bikini top and a towel. Her appearance is no cause for alarm, however, as her startling new look appeared to be in aid of a TV show.

After her acting hiatus, Sarah made her big return to a major TV show in her new Paramount+ series, Wolf Pack. Fans adore the star for her strong leading roles in fantasy dramas like Buffy, so her new character in the supernatural teen drama is a welcome hint of nostalgia for her fans.
Sarah Michelle looked unrecognizable
The new series tells the story of two teens whose lives suddenly change forever when a California wildfire awakens a terrifying supernatural creature.
In the series, which also stars Armani Jackson and Bella Shepard, the Cruel Intentions actress plays the role of Kristen Ramsey, a "highly-regarding expert in her field" who is drafted in to help catch the teen arsonist who started the wildfire that changed everything.

A second said: "I am really enjoying #WolfPack so far, and it feels so good to see Sarah Michelle Gellar back on [TV] I'm still narked the Cruel Intentions series never made it past the pilot."
