Caitlyn Jenner's BFF, actress Candis Cayne, dished to ET about changing society's perspective on the transgender community.

"It's huge, because it's starting to rewrite the way people see trans actors," Cayne told ET.

Cayne's transition reportedly began around 1996. She was known in the New York City nightclub scene before gaining national attention in 2007 when she took on the role of transgender mistress Carmelita on the ABC soap Dirty Sexy Money.
