Long before she was on Friends, Jennifer Aniston had a friend in Chaz Bono. Known then as Chastity (Bono underwent female-to-male gender transition in 2009), the two classmates posed for a locker room photo at New York's High School of Performing Arts in 1987.

"Every day a group of us would go to Chaz's house after school," Aniston, 42, recalled during an interview with Allure earlier this year. "I haven't spoken to him in awhile."

When asked if Bono's sex reassignment is confusing, Aniston responded: "Well, obviously, yeah. I mean, even for his -- her -- mother, I think. His mother. But, you know, good for her."

Bono, 42 -- whose parents are the legendary Sonny and Cher -- will make his Dancing With the Stars debut on September 19.
