Los Angeles: Coldplay star Chris Martin admits he has had only one serious relationship - with wife Gwyneth Paltrow.
The host of CBS Sunday Morning asked Martin if it was true that he`d only had "one serious relationship". Usamagazine.com quoted Martin as saying: "(That`s) right. I`m in it."
Martin and Paltrow married in 2003 and have two kids - Moses, 5, and Apple, 7.
The singer says that fatherhood has made him more focused.
"It`s made me more focused. And you have a purpose. I like what it does. Just the idea of having to work hard, so your kids are okay," Martin said.
