Bruce has made no official statement regarding his gender or any planned transition. However, his mother told the Associated Press that he sat her down for a long talk and what he told her was "a shock," but she was proud of him and would always love him.
In the new 30-second promo, a voiceover booms, "Bruce Jenner, on family" followed by Jenner saying, "Those are the only ones I'm concerned with. I can't let myself hurt them."
The voiceover says the interview will cover "the future, the decisions, the journey," but does not elaborate on what any of those entail.
A quote used in a previous promo is also repeated in this one: Bruce Jenner saying, "My whole life has been getting me ready for this."
The special will air Friday, April 24 at 9 p.m. ET on ABC.
