Jason Collins' Twin, Jarron, Says He 'Just Never Knew' His NBA-Star Brother Was Gay (VIDEO)

WATCH: How Jason Collins' Twin Found Out The NBA Star Was Gay

When professional athlete Jason Collins announced his homosexuality in April, the public instantly began acknowledging him as the first openly gay active NBA player. But to his twin brother, Jarron Collins, Jason's newly declared sexuality was a complete surprise that took a moment to get used to.

In this clip from their sit-down with Oprah for a special edition of "Oprah's Next Chapter," the Collins brothers open up about what happened when Jason told Jarron that he was gay. Jarron recalls, "[Jason] sat me down on a couch and said, 'Hey, Jarron, I've got to talk to you.'"

Jarron immediately sensed that the discussion was important. "We keep our relationship very, very light, but... he was serious in his tone and what he had to say," Jarron says in the clip. "It was very matter-of-fact. He said, 'Jarron, I'm gay.'"

That's when the shock set in. "I heard what he said, but it didn't quite register," Jarron tells Oprah. "It took a moment to process."

Once Jarron had processed Jason's statement, he had a series of questions for his brother -- and some, he admits, were "stupid questions, like, 'You're gay? Since when?'"

Jarron says that part of the reason he felt so blindsided by Jason's coming out was because the brothers have always had a close, open relationship. "We're very tight, obviously. Very, very close," Jarron says. "[Yet] I just never knew that he had an attraction to men."
