First, Donna Martin graduated, and now she's potentially getting a friend back.

Tori Spelling and Tiffani Thiessen, who co-starred in "Beverly Hills, 90210," have famously feuded for nearly a decade and hadn't spoken for 10 years. That's all changed.

Us Weekly is reporting that the two women recently reconnected at their kids' Los Angeles school.

Tori and Tiffani "hugged at a picnic," an onlooker told the mag. "They're getting back on the path of being really close again."

The once attached-at-the-hip pals ended their friendship in 2006 on acrimonious terms. Tori cheated on her then-husband Charlie Shanian with her current husband Dean McDermott. She famously told Charlie of her intentions to divorce him through their therapist.

That was the moment that shattered the Tiffani-Tori friendship.

The mother to Harper, 6, and Holt, 11 months, "took it personally," Us source said, adding, "She took Charlie's side over Tori's."

Time, however, seems to have healed all wounds.

"[Tiffani] and Tori have mutual friends and it's easier to get along," the source said.

In the 90s, the cast was largely inseparable and many of them have continued friendships to this day. Tori, though, became the odd man out after splitting with Charlie.

"All of a sudden I marry Dean, and I don't know what happened," Tori told Ryan Seacrest in 2010, 10 years after the show went off the air. "I lost all my cast members."

When the radio host asked specifically about Tiffani, who was cast as part-time villain Valerie Malone, the "True Tori" bluntly said, "She doesn't talk to me anymore."

Tori again ruffled the feathers of one of her former "West Beverly High" classmates when she revealed in an interview last year that she slept with both Brian Austin Green and Jason Priestley.

She said she was getting the "chills" while talking about Brian.

"I was a young girl," she said. "Brian and I were the youngest. We were 16, and I remember the first time I shook his hand, I had that ... I fancied him," she said.

As for Jason, she said, "It was off-set. It was our version of a summer romance. And that was it. And we stayed great friends for the rest of the run and beyond that."

Jason's response after the revelation, "I'm not getting into this... It's nobody's business... Either way…"
