Chris Martin isn't about to take Gwyneth Paltrow for granted.

The 34-year-old feels really lucky to be married to the GOOP Goddess, and not just because she's the only serious romance he's ever had.

In an interview with CBS Sunday Morning, Anthony Mason asked Martin if it was true that he'd only had "one serious relationship."

"[That's] right," the Coldplay frontman said. "I'm in it." 

When Mason pointed out that Martin's lack of serious girlfriends in the past was "pretty unusual" and told him he'd made "quite a leap," the musician quipped: "It's a big leap? What, from being a loser, to going out with an Oscar winner?"

He laughingly continued: "It's a giant leap. Let's face it: it's like winning the lottery."

Martin and Paltrow, who said "I do" in 2003, are parents to Moses, 5, and Apple, 7. 

So how has being a father changed Martin's professional life? "It's made it more focused," he said. "And you have a purpose. I like what it does. Just the idea of having to work hard so your kids are okay."

Anthony Mason's full interview with Coldplay and Chris Martin airs Oct. 16 at 9 a.m. EST on CBS Sunday Morning.
