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

Cayne is appearing on The Young and the Restless on Wednesday as a wedding planner for Abby and Stitch's upcoming nuptials. The role is of particular importance to Cayne, who is a transgender woman, and whose character’s storyline does not revolve around her gender identity.

"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.
