Ryan Seacrest was "shocked" when he saw Kourtney Kardashian's labor footage.

The Keeping Up with the Kardashians executive producer admits it was difficult to find a balance on how much detail to broadcast when the reality TV star gave birth to her son Mason, now two, and thinks the brunette beauty would have "loved" for the unedited film to have been screened.

"I remember looking at the raw footage of Kourtney having Mason, the baby. I'd never seen a delivery in that much detail. Half of me was interested, but I was shocked that she essentially reached down and delivered her own baby. And I was like, 'How much are we going to show of this?' And I realized that they were more qualified women to make this decision. She would have loved for us to air the entire thing. But I remember thinking, 'How far do we go?'"

Ryan is pleased with the "complete turn" which Kourtney's boyfriend Scott Disick has made in recent years to the extent he is now a firm favorite with fans: "He's become a very popular character. He's made a complete turn. I've seen him out, and people walk right past me and go take a picture with him. They are very excited to see him."

Keeping Up with the Kardashians first aired in 2007, but Ryan doesn't think the family have changed much since the show started and he thinks it has stayed popular because of the honesty it portrayed. Asked how the Kardashian family have changed, he said, "Salary. Besides money? Turnover with boyfriends and husbands. But the premise is still really simple. It's a family with a lot of love, a lot of craziness, a lot of chaos. There are aspirational components, too. But at the core, it's a group of sisters and a mom, and Bruce, who is just trying to figure out what's happening around him with this storm of women. That struck a chord early on. And they made a pact with themselves to be really honest. We don't stop at all when we shoot stuff for them."
