We know that all of Caitlyn Jenner’s kids are supportive of her transition, but how did her stepson-in-law, Kanye West, take it?

On the premiere of the E! docu-series, I Am Cait, Kim Kardashian and her rapper husband make an appearance and West praises Jenner for her bravery.

According to Us Weekly, West told her she’s "changing society in the most meaningful way” and that she’s responsible for "one of the strongest things that have happened” in this lifetime.

We will have to watch the premiere to find out if this was West’s first time meeting her, but he also brought up Kendall Jenner when he said, "You're a celebrity, your daughter is a supermodel, and you're saying this is who I am."

As we have seen in the promos, Jenner will experience many things for the first time as a woman during this docu-series, which premieres Sunday, July 26. She reportedly received an unprecedented $5 million payday for doing the series.
