Despite putting their lives in front of the cameras for the last decade, there is still a lot the Kardashians have kept under wraps — until now. In a tell-all interview with The Hollywood Reporter, the famous family spilled some juicy behind-the-scenes secrets about their highly successful reality show.

This month marks 10 years since the premiere of Keeping Up With the Kardashians and what started as a dinner table conversation between Kris Jenner and executive producer Ryan Seacrest has evolved into a pop culture juggernaut. You almost forget it was Kim Kardashian‘s sex tape that started it all. From Kourtney Kardashian crying in the bathroom to Caitlyn Jenner‘s transition, here is everything we didn’t know about the E! series until now:

The show was originally going to be called The Kardashians: Krazy With a K.

After the show was picked up by the cable network, it went straight into a production. However, execs were struggling to come up with a catchy name. According to Damla Dogan, the senior vice-president of development & programming at E!, “we were up against an airdate and didn’t have a title we loved.” Some options included, The Kardashians: Krazy With a K and Living Kardashian.

Caitlyn Jenner did not come up with the idea for the reality show.

In her memoir, The Secrets of My Life, Caitlyn hinted that KUWTK was her brainchild, writing, “The house is awash in puberty and adolescence and young adulthood and two parents with very different styles. It seems to me something is there for television. … Kris says she is the one who came up with the idea …”

However, Kris denies the allegations in the interview. “It’s so absurd. I’m not sure what the motivation was for her to say something like that. Maybe somebody should remind her that it’s called Keeping Up With the Kardashians.

Kourtney Kardashian was only one who was skeptical of the show!

The only member of the family that showed “resistance” was the oldest Kardashian sibling. “I remember in season one being like, “I have to go the bathroom,” and I’d cry in there as quietly as I could because I was still mic’d,” Kourt said. “I never want to cry in front of cameras.”

Khloé Kardashian did not want to do a spin-off with ex-husband Lamar Odom.

Turns out, it was the former NBA star’s idea to put their troubled marriage in front of the cameras. “I never wanted to do Khloé & Lamar; my ex-husband did. He sold it to E!, and I let it happen because I wanted him to be happy,” Khloé said. “I was the one who canceled it. It was way too much.”

Kim called Caitlyn Jenner’s transition the “most difficult thing to film.”

In 2014, Kris and Bruce Jenner finalized their divorce, and the following year Bruce announced he would begin living as a woman. “The most difficult thing [to film] was probably Caitlyn’s transition and just seeing my mom and Khloé having such a hard time,” Kim said. “We never really edited content before, but we did edit a bit of Khloé’s reaction just because she was so upset.”

Here’s to 10 more years!
