Gwen Stefani's solo career was "never meant to be taken seriously."

The singer has reunited with her original band, No Doubt, for their new album, Push and Shove and despite having sold millions of copies of her two solo records, her heart always lay with her original band.

"It just feels so much more natural being back in this mode. The solo records allowed me to indulge my girly side but it was never meant to be taken seriously. It was just like an art project that kept going longer than I expected. The group never ended - we always knew we'd come back to make this album."

Gwen, 42, also said her rocker husband, Gavin Rossdale from Bush doesn't listen to her ska-pop group - which also includes Tony Kanal, Adrian Young and Tom Dumont - as he doesn't like their style of music: "Oh, he's never been a fan of what we do. He's more into dark, indie stuff. But I'm not saying he doesn't think I'm amazing."
