Congratulations Tina Fey and Amy Poehler!

The comedians and real-life besties won a Creative Arts Emmy on Saturday for co-hosting "Saturday Night Live" in December, when the two memorably brought back their beloved Sarah Palin and Hillary Clinton impersonations. Fey, 46, and Poehler, 44, even broke new ground with their win, since it marks the first time in Creative Arts Emmy history that the best Guest Actress in a Comedy Series award is being shared between two actresses.

Comedian Bob Newhart presented the award. The funny ladies beat out stiff competion, including Christine Baranski for her work on "The Big Bang Theory," Melora Hardin for her work on "Transparent," Melissa McCarthy for her work on "Saturday Night Live," Laurie Metcalf for her work on "The Big Bang Theory," and Amy Schumer for her work on "Saturday Night Live."

The award also marks Poehler's first Emmy win ever, and Fey's ninth time taking home the big television honor.

Fey and Poehler co-hosted SNL on Dec. 19 and delivered the second best ratings in 22 months, according to Variety, following only Donald Trump's episode last November.

The Creative Arts Emmys are taking place Saturday and Sunday at the Microsoft Theatre L.A. LIVE in Los Angeles. An edited version of the ceremony will air on FXX on Sept. 17.

When ET caught up with Fey in March, she couldn't help but gush over another actress' performance -- Sarah Paulson as Marcia Clark in "The People v. OJ Simpson: American Crime Story." Fey also played a fictitious, highly-exaggerated parody of Clark in the first season of "Unbreakable Kimmy Schmidt."

"Thank God I did that before Sarah Paulson because Sarah Paulson is so good!" Fey exclusively told ET. "I'm obsessed with it!"

"I literally called and I was like, 'I need to fill out my paperwork for the Emmys,'" she added. "I've always been in as a writer and I need to join the acting peer group so I can vote for Sterling [K. Brown] and John Travolta and Courtney [B. Vance]. I changed my status for them!"
