Lance Bass came out when he was 21, but the 'N Sync member revealed that one of his bandmates discovered his sexual orientation purely by accident.

Bass, now 34, revealed that Joey Fatone was the first member to learn he was gay.

"Joey walked in on me with the guy I was dating just kind of sitting on my lap. Straight guys don't do that," Bass recalled.

Fatone was totally unfazed by the discovery and fully supported his friend and bandmate.

"He was like, 'Dude, I don't care.' I'm like, 'Surprise!'" Bass said. "Joey was just like, 'Dude, I don't care. I have so many gay friends -- I don't care.'"

Fatone wasn't the only 'N Sync member to react positively. Bass said the rest of the group was equally supportive of his reveal. "It was a few months after that before I told the [rest of] the guys," Bass said. "I don't think anyone was surprised."

Today, Bass is the godfather of Fatone's daugher Briahna and is engaged to Michael Turchin.
