That Girl Lay Lay Wants Kim Kardashian to Let Her Post Vid with North

That Girl Lay Lay -- a 14-year-old rapper who just landed her own Nickelodeon series -- is calling out Kim Kardashian for allegedly demanding she take down a music video ... but sources close to Kim and Kanye are questioning the motives behind the project from the beginning.

Here's the backstory ... TGLL shared a music vid that shows Kim's then 6-year-old daughter, North West, hanging out inside Kim and Kanye's home during a playdate while the young rapper lays down one of her tracks.

Shortly afterward, Lay Lay claimed Kim texted her demanding she take down the vid, and she had no idea why. However, it was Tracy Romulus, Kim's friend and the CMO of KKW Brands who was the one who actually sent the text ... and it wasn't to Lay Lay, it was sent to her dad.

A rep for the rapper tells TMZ ... Lay Lay feels hurt, and wants Kim to let her repost the vid because she doesn't think there's any good reason to take it down.

However, a source close to Kim and Kanye say they never gave permission for their 6-year-old to be featured in the music video, and believe Lay Lay's team used the old footage of North for publicity.

The source continues, "Lay Lay’s dad refuses to release the music video without footage of North because he is clearly trying to use her image as a source of publicity which is why North’s parents have an issue to begin with. It’s a matter of principle at this point and the answer is still no. He cannot use footage that was filmed of North taken inside her home during what should have been an innocent child’s play date for commercial purposes.”

We're told Lay Lay's father asked Kim and Kanye months ago for permission to use the footage of North, but hadn't heard back by July ... so he decided to post it, thinking it would be no biggie because they had approved another video in the past. Our Kim and Kanye source claims they never received any sort of communication asking for permission.

For context, the video was shot in March 2020 ... when Kim was taking some heat for not crediting another young artist, ZaZa, when North performed one of her songs at Paris Fashion Week. We're told Lay Lay now believes Kim only set up that first meeting, and subsequent TikTok as damage control for what happened with ZaZa.

Our Kim and Kanye source says that couldn't be further from the truth, and say they set up a playdate with Lay Lay after her dad reached out because North was a fan.
