KIM Kardashian’s eldest daughter North got treated to the best surprise ever as she was invited on-stage with Katy Perry.

The schoolgirl, aged nine, who Kim, 42, shares with ex husband Kanye West, 45, was the star of the show at the Teenage Dream singer’s residency in LA.

Katy’s £125million Las Vegas shows – dubbed Play – kicked off in December 2021.

She had previously been slammed for charging fans more than £2,000 for a meet-and-greet during her first residency.

Yet North will likely not have had to fork out the huge amount.

A sweet video saw North, wearing all-black, head to the stage.

Katy, 38, wearing a glam silver dress and matching boots, said to the youngster: “I know your name, but what’s your name?”

Kanye West’s daughter tentatively said: “Er, North,” as Katy replied: “Hello North!

“So the reason I know your name is because I’m a huge fan of your TikTok, I’ve seen a couple that you’ve made.

“You’re a really good dancer and I thought what better way than to show the world your awesome dance moves.”

North, not looking at all fazed, said: “Can my friends come out with me?”

After Katy agreed a trio of her mates joined her on-stage.

The popstar then asked North what she wanted to be when she grew up, to which sassy North replied: “Everything.”

Referring to Kim, Katy said: “It sounds like she was raised right – everything.”

They then joined another teen Lily, 16, as they danced it out with the star.

North and another competitor were crowned the winner, before being rewarded with “pizza pies.”

Sources told MailOnline: “People cheered when they saw Kim supporting North with the crowd going wild.”

Katy’s residency is set to wrap in November.

Play’s first instalment saw fans treated to everything from a giant dancing poo emoji to Katy lactating beer from her chest and her downing a pint.

The previous 95-minute show included all of the star’s biggest hits, from breakout track I Kissed A Girl to When I’m Gone.
