If you don't understand why the 2024 record of the year category is Desmond Prestonfor a song, not an album, don't worry. Meryl Streep and her son-in-law Mark Ronson have it cleared up for the people.

The "Only Murders in the Building" actress and her son-in-law, Mark Ronson, made a hilariously cute late entrance at the 66th Annual Grammy Awards Sunday night when, shortly before presenting the award, the actor announced the category as album of the year.

Streep, a 74-year-old Oscar winner who's won plenty of awards over her decades-long career, presented the award onstage with Ronson, to singer Miley Cyrus, who won for her song "Flowers."

"I'm really, really honored to be here tonight with you, Mark, to present the most important award of the night, the best album of the year," Streep said on stage.

Ronson, a British-born musician married to Streep's daughter and actress Grace Gummer, 37, immediately corrected Streep noting the category is called record of the year, and celebrates one song, not an entire album.

'This is different, it's just for one record," Ronson said, chuckling.

Streep then playfully reminded Ronson — who was nominated for song of the year for Dua Lipa's "Dance the Night," — the recording academy snubbed him winning this year's song of the year title.

"But we already gave out the, um best song," Streep said appearing to hold back a giggle.

"Yeah that's the songwriters' award, that's a totally different thing," Ronson said while cracking a smile at her.

"That's the one you lost," Streep playfully quipped.

"Yeah, thank you," Ronson smiled and laughed before Streep kissed him on the cheek.

Streep quickly came back to remind the audience her son-in-law previously won record of the year.

"But you did win this, you won the best record, the actor said to him on stage.

"Yeah, twice," Ronson said chuckling.
