Actress Glenn Close insists her twerking to "Da Butt" during the 2021 Academy Awards on Sunday was not scripted.

The 73-year-old A-lister lost her eighth Oscar Award bid on Sunday night.

The actress, who was nominated this year for Hillbilly Elegy, was asked a trivia question by Lil Rel about previous movie songs.

Lil Rel asked guests if "Da Butt" was actually nominated for an Oscar or not.

Glenn correctly said the song was by EU and that it was written for the Spike Lee movie School Daze.

She stood up and twerked to the track, sending fans into a frenzy online.

Questions arose as to whether or not the scene was scripted.

In a post on social media, Glenn confirmed that she knew about the question in advance. She said she received a little help from her friends: screenwriter Chris Terrio, Oscar winner Daniel Kaluuya and his pal Darrell Britt-Gibson.

"I knew that Lil Rel was going to quiz me about 'Da Butt' and all three guys helped me run through what I was to say," she explained. "Darrell insisted that I mention the Backyard Band, on top of E.U., Suga Bear and the whole DMV.

"I googled 'Da Butt' and watched Spike's music video so when Lil Rel asked if I could do the dance... you can actually see me think of the video," she said, while adding that her twerking was spontaneous.

"That part was completely spontaneous. Daniel, Darrell and Chris egged me on!!! It was ALL their fault.”

She concluded her post, "CONGRATULATIONS DANIEL on your BEST SUPPORTING ACTOR Oscar. You are completely brilliant. I now consider both Daniel and Darrell to be friends-for-life!"
