North has appeared onKUWTKsince she was born in June 2013 and has since been a regular on her mother’s social media. She also made hermodeling debutalongside Kardashian West andKris Jennerto front Fendi’s #MeandMyPeekaboo campaign.

With all the fame at just age 5, radio host Big Boy couldn’t help but ask Kardashian West, “Do you think North has more money than us? Like her own?”

The question amused the KKW Beauty mogul as she responded with a laugh, demurring, “North is good.”

North’s question about why her mom is famous comes six weeks after Kardashian shared that she and siblings Saint, 2, and 6-month-old Chicago have been pretty much in the dark about their mom and dadKanye West’s level of fame.

While North has been becoming more familiar with being on camera, her cousin Mason is already well aware.

“Mason calls [the crew] the filmers,” Kourtney added. “He used to be like, ‘Are the filmers coming? I want to show them my Legos that I’m building.’ Now he’s in a phase where he’s like, ‘I don’t like when the filmers are over.’ ”
