Jack White says Meg White was "uninterested" throughout The White Stripes career.
The 'Hotel Yorba' duo found fame in 2001 - a year after divorcing as a couple - becoming one of the biggest rock bands of the last decade, before splitting in 2011, but Jack claims drummer Meg never showed the same level of enthusiasm as himself about the band.
He said: "In The White Stripes it was impossible to share the good moments with Meg because she was very uninterested. If something nice happened, it wasn't like we would hug or have a drink. That wasn't what went on.
"We would record a White Stripes song in the studio and it would be me, Meg and an engineer. So we would finish a mix of a song and I'd say, 'Wow! That's pretty good!' I'd look around and Meg would just be sitting there, and the engineer would just be sitting there. So it'd be sorta like, 'OK... Let's just move on to the next one.' It was just me by myself. But it was the best thing for me. It taught me a lot about trusting my gut."
However, Jack, 37, added there were also many precious moments shared between himself and Meg that no-one ever got to see, or will ever know about.
He added to Esquire magazine: "It's strange to know that there's beautiful moments that no one will ever know about. It's whether I'm going to tell you, because Meg's never going to tell you. There's a sadness to that, a romance."
