Tina Fey is getting the last laugh, quite literally, in that Taylor Swift feud you probably forgot about.
The Unbreakable Kimmy Schmidt co-creator snuck in a hilarious and subtle reference to her public spat with Swift -- which began when she and Amy Poehler delivered a joke about the singer's dating life at the Golden Globes in 2013 -- into a new episode of the Netflix comedy.
Just months after their Globes hosting gig, Swift hit back at the funny ladies in a cover story for Vanity Fair magazine. Reciting a quote that Katie Couric allegedly told her, Swift declared: "There's a special place in hell for women who don't help other women."
(Mild spoilers ahead for those who haven't watched the second season of Unbreakable Kimmy Schmidt.)
In episode nine of Kimmy Schmidt's second season, Ellie Kemper's title character crosses paths for the first time with Fey's alcoholic therapist character, Andrea, while working as an Uber driver. After receiving a bit of unsolicited advice about prioritizing her own needs above others', Kimmy returns home to exchange words with her roommate, Titus (played by Tituss Burgess).
Earlier in the episode, Kimmy had sacrificed her own need for a shower so that Titus' Barbie dolls could soak out their new perms. ("Some of them don't have the face for it," he explained.)
"Happy people value their needs as much as otherses'," Kimmy quotes the drunken Andrea, removing the dolls from the shower.
"How could you do this to my Barbies?!" Titus fires back. "You know, there's a special place in hell for women who don't help other women."
Back in 2013, at the premiere of her film Admission, Fey exclusively told ET why she was surprised by Swift's humorless reaction to the joke.
"I did not see that one coming," Fey said. "It was a joke. It was a lighthearted joke."
Poehler, meanwhile, laughed off the criticism by agreeing with Swift.
"Aw, I feel bad if she was upset. I am a feminist and she is a young and talented girl," Poehler told The Hollywood Reporter. "That being said, I do agree that I am going to hell. But for other reasons. Mostly boring tax stuff."
The Barbie fight is just one of many memorable scenes between Kimmy and Titus this season. The stars gushed to ET earlier this month about "becoming best friends" and dialing up the musical theater side of the show -- but don't hold your breath for "Peeno Noir" part two!
"I don't know if it is about topping as much as it is about exploring the other areas of music that we can investigate and offer up that people will latch onto and make their own, just as they did with 'Peeno Noir,'" Burgess explained.
"Yes, it's a journey, not a destination," Kemper, 35, chimed in, to which Burgess agreed and gave a resounding, "Oh, yeah!"
