John Legend told Chrissy Teigen he loved her for the first time after they had drunkenly had sex.
The 'All Of Me' hitmaker - who has seven-month-old daughter Luna with his model wife - admits he did what he wasn't "supposed" to do when he declared his feelings for the 31-year-old beauty.
He recalled: "We were both drunk and had just had sex.
"You're not supposed to say I love you after you have sex, and you're not supposed to say it when you're drunk - but we did it."
However, Chrissy - who looked shocked at her 37-year-old husband's revelation - wasn't convinced he had remembered the moment accurately.
She shouted: "I thought it was during."
During the couple's appearance on 'Watch What Happens Live', they also candidly disclosed a number of public places where they have had sex, including John's dressing room on tour recently, a changing room in upmarket clothing store Fred Segal and during a presidential campaign event for President Barack Obama in 2007 or 2008.
Of the latter, John clarified: "It wasn't at the White House, to be clear. It was at a campaign event that we happened to be at.
"It was in the dressing room."
However, Chrissy again disagreed with his memory, and interrupted to say: "No, it was in the bathroom. The public bathroom."
But John said: "No, it wasn't public!"
The 'Lip Sync Battle' star previously revealed she and the 'Ordinary People' singer - who married in 2013 - were members of the mile high club, having had sex on their seats on a plane.
She recalled: "We were on our way to Thailand to see my parents, flying commercial first-class.
"We were under a blanket. We weren't even in one of those pod things. I feel like we should get a trophy for that."
