Bruce Jenner has yet to come forward and tell anybody that he is actually transitioning. Until then, we have to rely on reports from TMZ, People, and BuzzFeed, who are all 99% accurate sources of gossip, as if gossip could ever be "accurate."
The latest development is that ABC News' Diane Sawyer will get a sit-down interview with Bruce when he's ready to actually come out.
ABC News had no comment, but BuzzFeed's source appears certain that Bruce will come out to Diane around the same time Bruce's E! docu-series on his "journey" will be announced.
So, that's the latest word. Until then, any tabloids speculating on his transition should be taken with a grain of salt.
