The British singer admits in a new and rare interview that he feels really lucky to be married to Gwynnie - and not just because she's the only serious romance he's ever had.
In an interview with CBS Sunday Morning, Anthony Mason asked Chris, 34, if it was true that he'd only had 'one serious relationship'.
Chris replied: 'That's right. I'm in it.'
Mason pointed out that Chris's lack of serious girlfriends in the past was 'pretty unusual' and told him he'd made 'quite a leap.'
The musician joked: 'It's a big leap? What, from being a loser, to going out with an Oscar winner?'
He then laughingly continued: 'It's a giant leap. Let's face it; it's like winning the lottery.'
Chris and Gwyneth married in 2003 and are parents to Apple, seven, and Moses, five.
Chris also revealed how being a father has made him more focused as a musician.
He continued: 'And you have a purpose. I like what it does. Just the idea of having to work hard so your kids are okay.'
He was recently photographed lunched with Jay-Z - perhaps passing on dad advice to the singer whose wife Beyonce is expecting their first child in February.
He and Gwyneth are rarely seen together in public and never attend red carpet or celeb events together.
Iron Man actress Gwyneth recently said in an Elle interview that she understands why musician likes to keep their relationship private.
'He makes music for his fans, and he doesn't want people to conjure a lame famous couple when they're getting into his music,' she said. 'I get it.'
