On Tuesday's episode of Spelling's podcast, "MisSPELLING," Green confronted his "Beverly Hills: 90210" co-star about prior claims she made "about the relationship that we had" while the two worked together on the popular teen drama from 1990 to 2000.

Spelling said on her podcast in April that she and Green had a fling while working on "90210."

"I was young, and I was caught up in it," Spelling said at the time.

"I don't consider what we had and have, like a relationship, like a fling or like a, you know, 'Well, we were boyfriend and girlfriend for this period of time,'" Green said about 13 minutes into Spelling's podcast episode Tuesday. "It was a 10-year period, so we went through all sorts of things. So I was curious, though, why you labeled it as a relationship?"

Spelling immediately sounded flustered by Green's confrontation and noted that she "just got really hot."

Eventually Spelling said that in retrospect, she understands that she "perceived it differently than you did."

"I mean, yeah, I mean, I want to say it was a crush," Spelling said. "But it was more than that. There was, like, a summer. Correct?"

Green went on to describe their dynamic as a "strange chemistry" in which they were like "brother and sister" who would "tease" one another with "sexual" undertones -- but went on to vehemently deny they were ever a couple.

Spelling agreed about their dynamic but also seemed to stand by her claim that they did indeed have a fling.

After some more awkward back-and-forth, Green eventually said that their relationship was "much more" than just a romantic one.

"That almost felt disrespectful to me because it's like, no, we went through way more than just what normal people go through when they're dating," Green said.

But the conversation got particularly cringe about 32 minutes in, when Spelling mentioned the first time the two had sex, which apparently happened after a trip to Disneyland.

When Spelling alluded to it by just saying "then Disneyland happened," Green seemed completely confused.

"So I have those things sometimes, where it's, like, I have zero memory of that," he said as Spelling started to tell the story of their trip to Disney. "But please, fill me in."

Spelling explained that she had vivid memories of the "special" night because Green was the second person she had ever slept with, noting that the lead-up to it felt like it was "out of a John Hughes movie."

Spelling said they had been fighting all day, and while they were waiting in line for the Matterhorn ride, she finally asked Green why they were always bickering.

"You said, 'Have you ever thought, maybe, I always fight with you because I love you?'" Spelling recalled Green saying to her.

"Yeah, and you were probably saying 'I love you' like we're sister, brother, like, friends," she continued. "And I was like, 'He said I love you.' And then we started kissing."

"Wait, what? I love this story," Green said, surprised. "I feel I'm hearing a story of you and someone else right now."

"I feel like such a stupid girl right now!" Spelling exclaimed.

Spelling went on to explain that since they were making out in public, Green suggested they go back to his hotel room, where the deed was done.

Spelling said she was so excited that the next day she went down to the hotel's lobby and called their co-star Jennie Garth to share the news with her.

"She was the first person I was like, 'You're not gonna believe what happened, Brian and I slept together,'" Spelling laughed. "She was like, 'What?!'"

Green then noted, "I remember other times, but I do not remember that time at all. I don't know how that's possible."

Spelling, flabbergasted, jokingly asked him if his memory was so foggy because it was "before I got my boobs done?"
