Caitlyn Jenner's Older Children Won't Appear On Her Docuseries

After 65 years, Caitlyn Jenner is introducing herself to the world -- first with a 22-page Vanity Fair cover story shot by Annie Leibovitz and then with an eight-part docuseries that will air this July on E!

The series will give viewers a look into Jenner's life as a woman, and though a promo that aired at the NBCU Cable Upfront in May included her youngest daughters and stepdaughters, Jenner revealed to Vanity Fair that her oldest children, from her first two marriages, would not be appearing on the show.

Jenner told the magazine she was initially "terribly disappointed and terribly hurt" by Burt, Casey, Brody and Brandon's decisions to not be involved with the series, but it's something she's come to accept.

The magazine makes clear that Jenner's transition isn't an issue for her oldest children, who all appeared in Jenner's "20/20" interview with Diane Sawyer, in which she came out as transgender.

About a month after the interview aired, Brody told Extra, "[I'm] very proud, very proud. It's been a journey for all of us but we're very supportive and I love him to death. It's really great to see how happy he is now."
