ICYMI: Caitlyn was just announced a new partnership with MAC Cosmetics! During her interview, she opened up about wanting to support the transgender community with the brand.

“I saw that the proceeds were going, in those cases, mainly to AIDS and HIV causes, and I was wondering if they were interested in doing something specifically geared toward trans issues because we need funding,” she confessed.
