According to reports, Caitlyn Jenner is now dating Sophia Hutchins, a 21-year-old trans woman. For a long time, Caitlyn has been openly leery of dating. Like a lot of minorities, Caitlyn Jenner is very focused upon respectability politics -- she wants to look and act a certain way that she feels is more dignified.
In April 1991, one month after her divorce from Kardashian, Jenner married her second spouse, retired Olympian Caitlyn Jenner (then Bruce), who completed her transition to a woman, taking the name of Caitlyn in mid 2015. They have two daughters together: Kendall (born 1995) and Kylie (born 1997).
