Kim Kardashian's daughter North West makes surprise appearance on stage at Katy Perry concert

Sometimes it pays to be the daughter of the most famous woman in the world.

Kim Kardashian's nine-year-old North West was called onto the stage at a Katy Katy concert during the singer's Las Vegas residency.

The eldest child of the reality star and her rapper ex-husband Kanye West looked utterly delighted as she spoke with Perry at the concert over the weekend.

Kardashian, 41, shared several clips of her daughter's surprise stage debut onto Instagram as she watched on with pride.

"So the reason I know your name is because I'm a huge fan of your TikTok," Perry told West.

"I've seen a couple of them that you've made. You're a really good dancer, and I thought what better way to be a great dancer [than] to show the world your awesome dance moves?"

The California Gurls singer asked her young fan if she'd like to dance in front of the crowd, to which West replied with an adorable question: "Can my friends come out with me?"

"She's got friends, she doesn't wanna do it alone," Perry replied, as three of West's friends joined her on stage. "This is awesome."

West then pulled some moves alongside Perry's backup dancers, as her mum filmed gleefully from the audience. 

During West's on-stage moment, Perry asked the young star how old she was.

"You're 9, that's so awesome. You know, at 9 years old, I started singing. That's when I found my little spark," the singer said. "What do you want to be when you grow up?"

Her answer was typical of a nine-year-old: "Uh, everything," she replied.
