Brian Austin Green is spilling on what went on behind-the-scenes during his time on "Beverly Hills, 90210."

During an appearance on "Watch What Happens Live with Andy Cohen" Thursday, the 46-year-old star answered a fan's question about whether he ever hooked up with co-star Tori Spelling.

"We hooked up. We did," he said. "We were young, so that's what young people do."

Green almost answered differently first, but confirmed the romance after learning Spelling had already talked about it.

"No, no, we uh... wait, Tori said that we did?" he began.

"Tori said that you guys hooked up," Cohen confirmed.

Green also revealed he had a mini-rivalry with Mario Lopez, who was on "Saved by the Bell" in the '90s and he had a crush on Nicole Eggert, of "Charles in Charge" fame.

"Name one fellow '90s star we'd be surprised to hear you asked on a date," Cohen quizzed.

"I think it was probably Tiffani Amber Thiessen," he said. "But I didn't really ask her on a date, and then we dated. But I always sort of played the like 'I wait until someone comes to me,' because I don't deal with rejection very well."

"But you probably never got rejected," Cohen added before wrapping up the segment.'I’m lucky to be alive': '90210' star Shannen Doherty gets candid on breast cancer battle
