If Sarah Michelle Gellar's life was a movie, we have a feeling we know who would play her.
The 39-year-old actress took to Instagram on Friday to share her version of the Three Characters challenge, in which she described herself in three fictional characters -- and they’re all played by Shannen Doherty.

"Hey @theshando I've taken describe yourself in#threecharacters one step further...here's me in three characters played by you lol #ShannenDoherty," she wrote alongside a collage of Doherty.
Gellar's first pic was Doherty's take on Jenny Wilder from Little House on the Prarie, while her other choices were from Doherty's better known roles in Heathers and Girls Just Want to Have Fun.
Doherty quickly responded to Gellar's epic declaration of love with one of her own.
"My #fbf is with@sarahmgellar cause she's always made me laugh like this. And.... Just to date this picture, we were heading to a Ricky Martin concert...... Which was fantastic btw," she captioned a throwback snap of the pair.

This isn't the first time the two have gushed about their friendship on social media. Just last month, Gellar posted a sweet tribute to the Beverly Hills, 90210 actress as she battles cancer.
"I've always said she is one of the most loyal friends I've ever known, and now while she is facing the toughest journey of her life, she is sharing it with friends she has never met in the hopes of helping other people who are going through the same struggle," Gellar wrote on Instagram, calling Doherty her "muse." "That's a true friend #F**kCancer."
