The newest teaser from Bruce Jenner’s Diane Sawyer interview involves his famous family, which includes six biological kids and four stepchildren.

The interview, which is titled Bruce Jenner – The Interview will officially air on April 24 but ABC has been releasing small teasers leading up to it.

The latest features Jenner talking about sons Burt, Brandon and Brody as well as daughters Casey, Kendall and Kylie and stepchildren Kourtney, Kim, Khloe and Rob Kardashian.

“Those are the only ones I’m concerned with. I can’t let myself hurt them,” he said.

The first two promos only show Jenner saying, presumably about his transition, “My whole life has been getting me ready for this.”

This will be the first time Jenner, or any of his family members besides his mother, confirms the transition to become a woman. The interview will last two hours and cover his prominent career as an Olympian, leading up to the big decision he has faced in recent years to transition.
