Gwen Stefani’s tour troupe

Gwen Stefani’s kids had "the best time" on her tour.

The ‘Used To Love You’ hitmaker has revealed she took her children along for the summer shows and her son Zuma, eight, got involved behind-the-scenes.

Speaking on The Ellen DeGeneres Show, she said: "They had the best time. Can you imagine three little boys on a [tour] bus after you do a show like, ‘Get to bed!’ … It’s exhausting. But it was fun.

"Zuma was so into it … I have a quick change where I was changing costumes and stuff – he was working it. He had his flashlight, headphones; he walked me on and off the stage every single night. For two hours he worked back there – he was so into it."

Meanwhile, the 46-year-old singer – who also has Kingston, 10, and Apollo, two, with her ex-husband Gavin Rossdale – previously opened up about her split from the 48-year-old musician, admitting she went through "months and months of torture".

She said: "Nobody except for my parents, the people involved, and whoever they told [know specifics].

"Nobody would believe it if I could really say what happened. I went through months and months of torture."

Asked if she knew something was going on, she added: "All you have to do is listen to every single song I’ve ever written and it’s all there. It’s an ongoing theme that I’ve had for a long time."

Gwen is incredibly happy with Blake Shelton now but she admits they both had "trust issues" at first.

She said: "We were both having trust issues, as you would if you were us. It was like, ‘I have so many problems. How can I now be getting into another potentially huge problem? What am I doing?’"
