Tori Spelling is opening up about how she didn't talk to one of her Beverly Hills, 90210 co-stars for nearly 20 years following the end of the series.

Spelling appeared on the August 25 episode of Brian Austin Green's Oldish podcast, which he cohosts with fiancée Sharna Burgess and Tori's brother Randy Spelling, where she and Green reflected on their past relationship and how they lost touch after the 2000 finale of the popular drama series, per E! News.

"I remember crying that we were going to lose touch because we were so close," she said of their last interaction. "It was almost like going through a divorce or something. It's time to move on, but I'm also losing that human I'm with every day and have that connection with. What's going to happen now?"

The Scary Movie actress said that Green attempted to comfort her and reassure her "that it was gonna be OK," but that ended up not being the case as they didn't speak for almost two decades.

"I remember you said, 'We're always gonna be together. We're even all gonna go on vacations together,'" she recalled. "And that was the last time we spoke for 18 years."

Green claimed he tried to keep his world and "keep a connection going," but felt like Spelling didn't do the same, telling his ex, "It got to the point where I just never got that from you."

"It was just this thing of like, 'She just doesn't want to be my friend anymore,'" he said. "I genuinely felt that. I tried to visit you, I would call you. When that wasn't reciprocated at some point, I gave up."

Spelling admitted that Green's recollection was "pretty right on" and shared how her relationship at the time with fellow co-star Vincent Young, which she said wasn't "good," impacted her friendship with Green. She went on to marry Dean McDermott and welcome five children together before filing for divorce earlier this year.

"I shied away from you because you weren't a fan of the relationship," she said. "You had a good working relationship with Vince, but I don't think you felt like our personal relationship was something that was correct for me. My process was different and I would shy away from those that would really fight for me."

She also noted that his own relationship with co-star Vanessa Marcil, with whom he shares 21-year-old son Kassius, was "frustrating to see" and added to their complicated friendship at the time. However, she told Green that she "never stopped thinking about you and never stopped wanting to reach out and reconnect," while he said Spelling was like a "sister" to him.
