Bruce Jenner has come out as transgender.
The highly anticipated broadcast - happening right now - revealed what has been speculated for some time. That Bruce identifies as a woman.
In the first part of the interview, Bruce struggles to hold back his tears, as he says: "It's going to be an emotional roller coaster but i'm going to make it through.
"I've been thinking about this day forever and what I should do with my life. How do I tell my story, how do I tell people what I've been through. I've been thinking about this day forever."
