Brian Austin Green doesn't remember Disneyland sex with Tori Spelling

Tori Spelling and Brian Austin Green have different recollections of what happened between them back in the day.

As Spelling welcomed her former Beverly Hills, 90210 costar on the Nov. 4 edition of her misSPELLING podcast , she recalled that they had a romantic interaction — their time sleeping together — during a Fox event at Disneyland.

He wasn't so sure at first.

"Wasn't it at Shannen's house?" he asked, seeming to refer to the late Shannen Doherty , who was their friend and costar. Doherty died in July after years of struggling with cancer.

"I feel like such a stupid girl right now," said Spelling, who played Donna Martin, the long-term girlfriend of Green's character, David Silver, on the teen drama that ran from 1990 to 2000.

Green reassured her that she shouldn't.

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

Spelling said Green told her he loved her during the same excursion, and they shared a kiss in public.

"And then you're like, 'Do you want to get out of here?'" Tori reminded him, saying it was something like you'd see in "a John Hughes movie."

The first person she told about the encounter was another of their costars, Jennie Garth , who played David's stepsister and Donna's best friend, Kelly Taylor. Garth and Spelling have remained particularly close over the years.

Spelling and Green agreed, however, that they shared a connection that was often romantic.

Green said they had a "strange chemistry, like a sexual chemistry that we would kind of tease each other with a little bit." They were always good friends, he said, and sometimes argued like siblings.

"We covered the gambit of what a relationship could be, which is why then, when people come to me and be like 'Oh, yeah, so you and Tori were dating for a while, right?' That's too easy of a label for me," Green said. "We were much more than dating."
