Actress Youn Yuh-jung, who won an Oscar for Best Supporting Actress for her role in "Minari" last year, presented this year's Best Supporting Actor award at the annual Academy Awards in Los Angeles on Sunday.

"I'm very happy to be back in Hollywood," she said. "My mother used to say, 'You reap what you sow.' I should've listened to my mom. Last year, I complained about my name being mispronounced in public, and I'm so sorry because I've looked at the incredible nominees of this category that I have to pronounce," she said. "Please forgive me in advance."

The joke referred to her acceptance speech last year, in which she wished that non-Koreans could say her name correctly.

Troy Kotsur, who plays a fisherman in Apple TV's critically-acclaimed "CODA," became the first deaf man to win an Oscar for acting.

Youn called his name in sign language before announcing him as the winner, and held the trophy for him while he gave his acceptance speech.
