Childish Gambino made Grammy Awards history - but nobody knows where he was

Childish Gambino has made Grammy Awards history by winning both song and record of the year.

It's the first time a rap song has won both categories - although Gambino did not attend or perform at the event.

He was the first artist to be absent from collecting one of the "big four" Grammys since Amy Winehouse in 2008.

Gambino - aka actor Donald Glover - beat competition from Drake, Lady Gaga and Bradley Cooper in both categories.

Ludwig Göransson, who co-wrote "This is America," accepted the award but when asked by reporters where Glover was, even he had no idea.

"I haven’t talked to him yet, but I’m going to call him after the award show, and I’m sure we’re going to have a little conversation,” Göransson told reporters following the win.

The rest of the "This is America" team who talked to reporters backstage also had no idea.

Riley Mackin, who also worked on the song, said he's not sure where Glover was either.

"The last time I've seen him was a couple days ago, and he walked out and I haven't seen him since," Mackin told reporters. "I think anything Donald does is a little strange."

Glover declined a performance spot for the Grammys, producer Ken Ehrlich told The New York Times.
