Kim Kardashian thinks that Caitlyn Jenner looks so good as a woman that she is comparable to her daughter Kendall. That’s what Kim told her transgender stepfather in the first episode of “I Am Cait,” the documentary series that showcases Jenner’s new life as a woman.

"You know, the one thing I'm really shocked about is how skinny you are. You literally look like Kendall – like Kendall's mom!" said Kim to Caitlyn in a scene from the show. Several media outlets were invited to a screening of the first episode of the series on Tuesday. The Mirror reports that Kim was seen “fawning” all over Caitlyn. The pregnant reality star told her that she looked beautiful and that she looks a lot like her supermodel daughter.

Kendall is Caitlyn’s fifth child and her first with Kris Jenner, who is also Kim’s mother. Kim admired her stepfather and told her that it’s now her time to shine. However, People reports that Kim also gave Caitlyn some stern advice.

“You look amazing. It's your time, but you don't have to bash us [Kardashians] on your way up." Kim reportedly said. To this, Caitlyn responded by repeating something that she had been saying from the first moment that her transition came to light. She said that she never wants to hurt her family most especially her children. 

Caitlyn has six biological children and four stepchildren from three marriages. She has Cassandra and Burt from first wife Chrystie Scott; Brandon and Brody from second wife Linda Thompson; and Kylie and Kendall Jenner from third wife Kris, who also brought her four children from a previous marriage, Kourtney, Kim, Khloe and Rob Kardashian, to the family.

According to a review by the New York Times, the first episode of “I Am Cait” offers an extended look at Caitlyn now in her fully transitioned state. She’s a stark contrast to the Bruce Jenner that has been seen in “Keeping Up With the Kardashians” since 2007. However, she brings to mind the Bruce Jenner of his Olympic days. “ Once again she’s a polished, effective pitchwoman, selling acceptance and transgender pride as capably as she once sold breakfast cereal,” said the review.

‘I Am Cait” premieres on Sunday, July 26 at 8:00 pm EDT on E!.
