While we're all used to seeing her as Bruce in Keeping Up With The Kardashians, this will be her first TV appearance as Caitlyn.
During the one minute teaser, Caitlyn, 65, discusses the decision to finally start living life how she believes she was intended to.
She says: "So many people go through life with their own issues. No matter what their issues are. Our issues seem to be gender identity.
"But how many go through life and waste their entire life because they never deal with themselves to be be who they are?"
Caitlyn also admits she's only just realising the pressure on females in particular to look good all the time.
Discussing the first time she had her make-up professionally done, Caitlyn says: "What a difference."
The trailer then sees Caitlyn and a friend going for a drive, and she reflects on what it would feel like to be accepted as 'normal'.
When her friend tries to reassure her, Caitlyn replies confidently: "Put it this way, I'm the new normal."
