“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 said with a laugh. “He was like, 'Dude, I don't care.' I'm like, 'Surprise!' Joey was just like, 'Dude, I don't care. I have so many gay friends. I don't care.'”

“It was a few months after that before I told the [rest of] the guys. … I don't think anyone was surprised,” Bass added.

Bass publicly came out gay on the cover of People magazine in 2006.

His latest reality project, Celebrity Home Raiders, premiered Thursday on cabler Lifetime.
