I Am Cait premiere reveals Rob Kardashian's touching phone call to Caitlyn Jenner after her Vanity Fair debut

The Kardashian and Jenner kids may not agree on everything, but they've all been fully united in their support of Caitlyn Jenner. Now we get to hear Rob express his for the first time.

In a sweet scene from the premiere episode of I Am Cait, the 65-year-old gets a phone call from the Kardashian family black sheep congratulating him on the Vanity Fair cover. Then Kim buzzes to announce that her stepdad has just broken a pretty impressive record.

The chat with Rob is the real revelation here as it's been some time since we've seen the reclusive 28-year-old or even heard him speak.

Watch the video above to hear Caitlyn's conversations with Rob and Kim.

We love that Caitlyn and Rob are still close, but her easy banter with Kim leaves us wanting more. Their I Am Cait scenes should be some of the best.
