The 'Gravity' hitmaker wasn't impressed when he caught a glimpse of himself in pictures shared online that were taken during the ceremony telecast on Sunday (10.02.19) so took advantage of a pause between festivities to return to his house for a trim.

John explained he had time for the cut before attending the Sony Music Entertainment 2019 Post-Grammy Reception because "there's something in between the show and the afterparty, and it's called waiting around doing nothing."

He also praised his baber for quickly responding to his grooming emergency.

He said on an Instagram Live post: "You might be aware that I've got my hair cut in between, since I last saw you in between the Grammys and now.

"I got my hair cut because I look back at a picture from the Grammys and I said, 'That won't do. I need another haircut.' Shout out to my barber Nick, who came to my house."

The 41-year-old musician described the moment as "the baller-ist thing I've ever done."

He added: "I used the Grammy Awards telecast as a mirror.

"He used a Grammy Awards show as a mirror. He checked his hair in the Grammy Awards. And then he got his hair cut. Top that."

John had appeared at the Grammys to present Song of the Year - which went to Childish Gambino for 'This Is America' - and host Alicia Keys revealed the pair actually have "joint custody" of a 2004 award.

She said: "I wanted to share with you a little story. I have been super blessed to win 15 Grammys. Pretty cool, pretty cool.

"And in 2004 I dreamed about winning song of the year for 'If I Ain't Got You'. So, when my hero, Stevie Wonder, opened up that card and started to read in braille, I just knew he was going to feel my name. My name.

"I ain't got that Grammy. But don't worry, it's okay. Because this story has a really happy ending. Because John said, I agree, Alicia, this should have been yours and he literally broke the Grammy and wrote 'If I ain't got you' with my name on it and gave it to me."

Alicia showed off her half of the award, and John then walked out with his part of the prize.

He said: "This has got to be the coolest joint custody agreement in showbiz history."

Alicia agreed: "We're putting it back together, it belongs together."

But John stressed: "Just for one night only."
