After moving across the country to L.A. together, Greg Mathis Jr. is ready to reach another relationship milestone with boyfriend Elliott Cooper on E!'s Mathis Family Matters.

As he explains in this sneak peek of the upcoming July 3 episode, "A big part of why I wanted to come out here is because I do want to take a more public track as an LGBTQ advocate. And on the road to being more public, I wanna do a public announcement about my sexuality."
