Giving the most screen time to Caitlyn of any trailer we've seen yet, the clip features an appearance by her mother Esther, who explains, "My first feeling was, 'I lost my son.' Then I thought, 'You know what? I'm gaining.'"

Other notable cameos include daughter Kylie Jenner, daughter-in-law Kim Kardashian, Candis Cayne (who reportedly will be a regular on the series) and a number of trans youth whom Caitlyn visits at the Los Angeles LGBT Center.

And oh yes, she sabres a champagne bottle!

Of course there are less celebratory moments, as a tear-filled Caitlyn reveals: "I want them to be proud of their daddy," referring to her 6 children and 3 step-children.

Watch the new trailer below.

I Am Cait debuts July 26 on E!
