In her latest Instagram post, the “cancer slayer” wonders if she accidentally killed Gellar, who played Buffy in “Buffy the Vampire Slayer,” after what looks to have been an intense workout. Gellar, however, eerily opens her eyes while lying on the ground, eliciting a scream from Doherty.

“Did I or didn’t I….. the #slayer and the #cancerslayer,” Doherty wrote as the caption for the video. “@sarahmgellar being supportive thru thick and thin. Love this woman #friendship.”

The pair has been best friends since the 90s, and Gellar has been a huge support system for Doherty while she’s been undergoing treatment for cancer. Doherty, who recently finished radiation therapy, appears to be doing and feeling well.
