Daniel Kaluuya talked about his parents having sex during his Oscars acceptance speech

• Daniel Kaluuya won best supporting actor for "Judas and the Black Messiah" at the 2021 Oscars.
• In his acceptance speech, Kaluuya said he was grateful that his mom and dad had sex.
• His mom and sister were watching from London, and their live reactions were caught on camera.

The 2021 Oscars kicked off with a flurry of wins for British filmmakers, with Emerald Fennell and Christopher Hampton both winning writing awards. But it was supporting actor winner Daniel Kaluuya who had the best moment of the first batch of Oscar winners with a hilarious speech.

Kaluuya, who won for his role in "Judas and the Black Messiah," started off his acceptance speech at Union Station by thanking God. He ended the speech by saying he was grateful his parents had sex.

"My mom, my dad - they had sex," Kaluuya said. "It's amazing! I'm here!"

To make things more interesting, his mom was listening to her son's entire speech over in London at the Oscars' UK hub for the night. And her priceless reaction was caught on camera.

Twitter immediately latched on to that moment. Movie fans are loving the speech and many are already saying it will go down in Oscars history as one of the most entertaining ever.

Daniel Fienberg, TV critic for The Hollywood Reporter, tweeted: "Daniel Kaluuya outing that his mother isn't a virgin on national TV was certainly a moment."

Meanwhile, Barstool Sports host and podcast host Francesca Mariano tweeted: "Not going to get a better moment tonight than cutting to Daniel Kaluuya's mom and sister after a sex joke."

It's safe to say, fans loved Kaluuya's win and his acceptance speech. Writer Hunter Harris tweeted: "I would like to thank Daniel Kaluuya's parents."

Kaluuya, who some argued should have been nominated as a lead rather than in the supporting category, won for playing Fred Hampton, chairman of the Black Panther chapter in Chicago. He starred opposite Lakeith Stanfield, who was also nominated for best supporting actor.
