Bruce Jenner has come out as transgender.
The 65-year-old made the revelation during a special with Diane Sawyer on ABC's "20/20" Friday night.
"I'm me. I'm a person. this is who i am. I'm not stuck in anybody's body.My brain is much more female than male," he said.
Named the "world's greatest athlete" when she won the decathlon gold at the 1976 Olympics, Jenner joined the Kardashian family when she married Kris in 1991. She became a stepparent to Kourtney, Kim, Khloe and Rob Kardashian, and later welcomed two daughters with Kris, Kendall and Kylie Jenner. She has been a central figure on the family's E! reality show since its premiere in 2007. She and Kris announced they were splitting in 2013 after 22 years of marriage.
The former Olympian was previously married to Linda Thompson and Chrystie Scott, and had two children with each of them. Scott recently said she supports Jenner "in whatever he chooses to do."
