Gwen Stefani has dismissed rumours No Doubt’s reunion has been marred by tension between bandmates, insisting they've overcome that "air bubble".

The band recently embarked on a new tour, ending a five-year hiatus, during which Stefani released two platinum-selling solo albums, worked on her clothing line L.A.M.B. and welcomed two children - Kingston, three, and Zuma, 10 months - with husband Gavin Rossdale.

Reports suggested Stefani struggled to fit back into the band, but she insists any tension has disappeared since a "heated conversation" with bassist and ex-boyfriend Tony Kanal over the band's cover of Adam and the Ants' Stand and Deliver.

She tells America's Elle magazine, "Everybody's making it like there's all this tension, you know, like I stepped away from the band and now they're jealous of me, and look, maybe there is a little bit of that... but some fights aren't really what they seem. I think it was a little about the song, and a little about our coming back together. There was this air bubble that needed to pop, you know?"
