Donna Martin graduates! And then she spills all.
Tori Spelling is talking about her infamous inheritance, or lack thereof, from her father and legendary television producer Aaron Spelling and what Beverly Hills, 90210 costars she hooked up with in a sneak peek of Tori Spelling: Celebrity Lie Detector.

According to People, after her father’s death in 2006, she reportedly only received a small portion of his $500 million fortune in her inheritance. The True Tori star addresses the rumor that she only received $800,000 in his will, and says it is true. The clip cuts off before we can see if the polygraph says she is lying or telling the truth.

Spelling also talks about her romance history with the cast of Beverly Hills, 90210. In another sneak peek, Spelling opens up about her relationship with then-costar Brian Austin Green.

"I just got chills. I was a young girl," Spelling says. "Brian and I were the youngest, we were 16, and I remember the first time I shook his hand, and… I fancied him!"

Spelling is also asked if she had a sex with any other costars.

"Half my friends don't even know this!" Spelling says after host Louise Roe eliminates Ian Ziering.

Fans will have to tune in to find out if Spelling reveals if the guy in question is Jason Priestly or Luke Perry.

Tori Spelling: Celebrity Lie Detector airs after The Unauthorized Beverly Hills, 90210 Story on Lifetime on Saturday, Oct. 3. The 90210-themed night of television starts at 8pm.
