One of Bruce Jenner's ex-wives expressed her support after Jenner confirmed Friday that he's transgender and identifies as a woman. Also standing firm behind the former Olympic athlete: his four oldest children (the ones not regularly seen on Keeping Up With the Kardashians), despite the "very complex relationship" he had with them and his absence in their lives while they were growing up. Jenner has acknowledged pulling back from his older kids—Burt and Cassandra with first wife Chrystie Scott, and Brandon and Brody with second wife Linda Thompson, per ABC—as he struggled with his gender identity, telling Sawyer that in "the big formative years for them, I was really struggling with these issues. I talked to all the boys about this after the fact, that, yeah, I didn't do a good job. And I apologized to my kids for that."
In clips from Diane Sawyer's 20/20 interview that didn't air Friday, daughter Cassandra Marino said the Olympic athlete "disappeared out of our lives, especially out of my life. So … I'm looking forward to this next chapter," per ABC News. Brandon also notes the pain he felt, but like his other siblings, he's ready to forgive and move on. "Us missing, you know, a time of our lives is still probably the hardest thing for us to deal with," he told Sawyer. "We're trying not to look back. We're just looking forward." Oldest son Burt has especially kicked into protect-Dad mode, apparently tweeting about fair-weather fans on Saturday, according to Perez Hilton and other media sources. "Having a hard time not putting a few people on blast who were not supporters before hand, but want to act like they were all along," read the since-deleted tweet. Hilton speculates Burt may have been talking about Kris Jenner. (Read more Bruce Jenner stories.)
