In the interview, the NBA player, his twin brother and his parents sit down with the legendary host in the clip (above), and because it's just a preview, we're getting anxious to see the whole conversation.
It's sad to think that Collins has already received death threats for coming out, but we're sure Oprah will touch on that subject, and hopefully make things better!!
The complete interview airs Sunday, May 5 at 7:30/6:30c., but for now, ch-ch-check out the video (above)!!
