Gavin Rossdale is ''lucky'' to be married to Gwen Stefani.

The Bush frontman and the No Doubt singer have been married for over 10 years and have sons Kingston, six and Zuma, four, together and Gavin says being with Gwen is always ''interesting''.

He told E! News: ''To be with one person for a very long time actually gets more interesting. I'm into that. She's a great girl. I'm lucky.''

While their marriage is strong now, Gwen previously admitted it hasn't always been easy.

She said: ''You feel proud. There are just so many rewards that come with it. You have to work at it. But, actually, it's fun to get to this point. Because you learn so much about somebody. It's like these wars that go on and then you kind of get through it to the other side, and it's like, Wow. And obviously, you get stronger.

''And then having kids takes the whole relationship to another place. It is the ultimate collaboration. Both of us have such strong opinions about how it should be, and it's really fun to do it together.''
