WATCH: Transgender Tween Tackles Challenge Of Dating

Barbara Walters’ follow-up interview with Jazz is finally going to air Saturday night. Jazz, age 12, is transgender and has been raised as a girl since she was three. Walters previously interviewed Jazz and her family in 2007 when she was six. Now, as she reaches the age of puberty, she faces not only the challenge of blocking the effects of testosterone, but navigating the tricky world of teenage dating. Walters shared this preview of tomorrow night’s 20/20 featuring Jazz texting with a boy she met about her identity.
