WATCH: The moment Kris Jenner meets Caitlyn for the first time
As expected, exes Caitlyn and Kris Jenner met for the first time in front of a tv crew.
Caitlyn was married to Kris for 22 years when she was known as Bruce and they split in 2013. They have two daughters together Kendall (20) and Kylie (18) and Caitlyn is stepfather to Kim, Khloe, Kourtney and Rob Kardashian.
And viewers of I Am Cait will see a polite introduction between the two exes before a showdown over Caitlyn's comments in the media about her ex-wife.
Caitlyn (65) greets Kris (59) at the door of her Malibu mansion saying: "Well look who's here", to which Kris responds "Oh my goodness."
Earlier in the episode, the Olympic gold medallist says she hasn't spoken to the Kardashian matriarch in a year and calls her to meet face to face for the first time since transitioning.
Caitlyn has come under fire from her family for comments she made in her now world famous Vanity Fair interview in whcih she described Kendall and Kylie as a "distraction".
While chatting for the E! docu-series I Am Cait, viewers see Kris tearfully confronting her ex, saying: "You're sensitive and amazing to all these new people in your life. But you're not so sensitive and amazing to the family that you left behind.
"When you feel like you gave your whole life to somebody...the sum of it all was you were a distraction."
Caitlyn responds: "I try to do everything I can to be nice, reach out. You have to see it from my perspective... be an ally when it comes to dealing with the kids."
The episode is set to air in the US on September 6 on E!
