The 47-year-old singer, designer, and 'Voice' coach may seemingly lead a glamorous life but Kingston, 11, Zuma, nine, and three-year-old Apollo - her kids with ex-husband Gavin Rossdale - aren't impressed by her work and never want to be involved.

Speaking to reporters at a preview for her L.A.M.B. & gx Eyewear collection, she said: "When you're a mom, they don't want to know anything about what you do. It's all about them, and that's their job.

"I almost had them come with me today, because it's their last week before school and stuff.

"They would have hated it here. They don't want to be part of anything. They just want to be the kids and you be the mom."

However, Gwen - who is in a relationship with country singer Blake Shelton - admitted the boys made an exception when it came to her small role in the 'Trolls' movie, though she's baffled as to why they were so impressed.

She said: "When I was in the 'Trolls' [movie], for some reason that was a big deal.

"They still talk about it. They'll be like, 'Mom! When you did 'Trolls', did you...?' I'm barely in it. I have like one line or something. They get pretty excited about that, but this [event] they wouldn't."

The 'Hollaback Girl' singer recently admitted she had always planned to be "really free" with raising her kids, but quickly learned they appreciated having boundaries in place.

She said: "I was in a band and free my whole life, so I always thought I would be really free with [my kids] and do whatever I wanted, like, 'Oh, I'll take them out of school.' But you learn that when they have boundaries is when they feel the safest.

"The hardest thing to do is having a discipline chart and follow up on all those things. It's work, you know? But that's where you get the results."
