WATCH: Kathryn Hahn becomes first woman to Show her Naked Bum In the Marvel Cinematic Universe

Kathryn Hahn is officially the first woman to bare her bottom in the Marvel Cinematic Universe.

On Monday’s episode of “The Jennifer Hudson Show,” Hudson presented the “Agatha All Along” star with a gift to celebrate the cheeky milestone.

“You do realize you are the first woman to show your butt in the Marvel Cinematic Universe?” Hudson said, as the audience cheered.

“I am. I didn’t know it at the time,” Hahn replied. “But also to know that it’s behind Thor is pretty great. Thor, me — just our butts encased in gold,” she joked, nodding to fellow MCU actor Chris Hemsworth, who showed off his naked rear in 2022’s “Thor: Love and Thunder.”

“We got you something to commemorate that moment,” Hudson said, presenting Hahn with a black and purple plaque that read “First Woman to Show Her Butt in the Marvel Cinematic Universe.”

Hahn gushed over the award. “This is like I walked on the moon!” she joked. “This is the best! I can quit now.”

Elsewhere in the interview, the “Agatha All Along” star ― who first played the title character, the charismatic witch Agatha Harkness, in the 2021 hit series “WandaVision” ― revealed that the moment of dishabille was actually her idea.

“When we see Agatha at the beginning [of the first episode], she’s completely without her powers,” Hahn explained. “She has to bust out of this spell, or is helped out of this spell, by some mysterious characters. And I think when you first see her, when she first realizes… I think the description [in the script] was like, ‘She puts on a robe and goes outside.’”

Hahn then recalled thinking that Agatha’s first instinct probably wouldn’t be to reach for a robe, given her state of mind in that moment.

“I was like, ‘I wonder if she would put on a robe, because she is in a feral state,’” she told Hudson. “Like, I think that she was just feral. Like, she wouldn’t even be thinking about [it].”

“That’s commitment,” Hudson noted, prompting Hahn to jokingly add: “There was a lot of double-sided tape.”

Episodes of “Agatha All Along” ― which also stars Patti LuPone, Aubrey Plaza, Sasheer Zamata, Debra Jo Rupp and Joe Locke ― hit Disney+ on Wednesdays.
