You might know Kourtney Kardashian, eldest daughter of Kris Jenner and Robert Kardashian.
And you might know that Kourtney has three kids of her own: Mason, Penelope, and Reign.
Keeping Up With the Kardashians started in 2007, so we've pretty much watched all the kids grow up before our eyes.
But even though the kids have made many appearances, Kourtney revealed that they don't watch the show.
In an interview with Cosmo, Kourtney said:
They've seen some of it, but no. I was in the shower, he [Mason] woke up, and it happened to be on. He was like, "Who is Blac Chyna? And Kiki [Kim] showed Larsa [Pippen] her vagina!" I was like, this is why they don't watch the show. Some of the content is just not appropriate.
