Glenn Close’s viral ‘Da Butt’ dance at Oscars wasn’t scripted

Case closed.

The instant-classic Oscars moment in which Glenn Close started dancing to the Experience Unlimited song “Da Butt” wasn’t scripted, a representative for the actress told NBC News.

“The quiz, as noted, was requested of the participants and partially scripted. The dance was NOT scripted,” the publicist told NBC News.

The fun segment involved comedian Lil Rel Howery walking up to different nominees at Union Station in Los Angeles Sunday evening and quizzing them on whether various songs won Oscars in the past.

When he asked Close about “Da Butt,” which appeared in 1988’s Spike Lee-directed “School Daze,” Close quickly identified the R&B song.

She then broke into the dance, which delighted her fellow audience members at the 93rd Academy Awards, as well as fans on social media.

ABC television executive Rob Mills told Variety that Close’s dance was “something nobody expected.”

“You could see the way she was talking about it,” he told the outlet. “She’s very learned, and whatever it is, whether it’s a role or something she’s doing for the Oscars, she does her research. So I think it was very clear. If Glenn Close had not heard ‘Da Butt’ before this, she knew it when Lil Rel asked her about it.”

Close, 74, was nominated for Best Supporting Actress for her portrayal of Mamaw, the mother of Amy Adams’ character, in the Netflix drama “Hillbilly Elegy,” which was directed by Ron Howard.

Close is an eight-time Oscar nominee but has never taken home a trophy.

Sunday’s honor for Best Supporting Actress went to Yuh-Jung Youn, who played the grandmother Soonja in “Minari,” a drama about a Korean-American family with dreams of starting a new life in rural Arkansas.
