The 'All of Me' singer - who performed 'City of Stars' and 'Audition' from 'La La Land' at the Academy Awards - was joined on the red carpet at Sunday's (26.02.17) ceremony by his stunning wife and couldn't help but repeatedly step on the train of her lavish Zuhair Murad gown.

He admitted: "This dress will be stepped on at least 30 times tonight. It just might fall apart.

"Every Oscars, I step on her dress. Every train she's had, I've stepped on."

Chrissy quipped: "Oh, it's been 11 years! I'm very used to it."

Earlier in the week, the 38-year-old singer shared a video of his 10-month-old daughter Luna helping him rehearse for his performance, but he joked the tot hasn't inherited his musical talents.

Asked about Luna's piano skills, he laughed to 'Entertainment Tonight': "It's terrible. She's not good at it."

But he is hopeful she will grasp the instrument when she's older.

He added: "But I'm so happy that she seems to spark up when music is on, so that's a start. And then we'll teach her to play it at some point later, hopefully."

And John also admitted he is impressed by his model wife's vocal abilities.

He said: "Her mommy is actually quite musical. People don't know that. She can sing better than you think. This is my honest opinion."

Asked if they could duet in the future, he said: "Who knows what the future brings?"

However, his 31-year-old spouse didn't seem so convinced and urged her husband to "stop talking about it".
