Shaquille O'Neal's estranged wife, Shaunie O'Neal, tried to meet with his mistress, Vanessa Lopez, to convince her to go public with her affair with the Diesel.
That way, she could derail their prenup, according to a report.
Shawn Darling, the man suing Shaq for hacking his computer, is writing a tell-all book in which he plans to expose Shaunie's plan to score all Shaq's cash.
As a result, "Shaunie is freaking out," a source told Radar Online. "She'll probably be deposed in his case and does not want this information to come out."
According to the source, when Shaunie discovered that Shaq was having an affair with Vanessa Lopez, she devised a plan to expose Shaq as an adulterer.
"She reached out to Vanessa last October through Shawn, who was working for the family at the time," the source revealed. "Shawn called Vanessa and told her Shaunie wanted to meet her in the food court at her local mall in Orlando."
Shaunie O'Neal and Vanessa Lopez were to discuss "an incentive." Diabolical."She wanted to convince Vanessa to go public about her affair with Shaq so Shaunie could accuse Shaq of adultery, which would nullify their pre-nup."
The plan ultimately backfired, however, when Lopez called Shaq and informed him of Shaunie's plan and was advised by his attorney not to meet up.
The tell-all book poses a host of legal issues for Shaunie.
"Shaunie signed a confidentiality agreement when she married Shaq," the source said. "But then she went and told Shawn Darling all sorts of personal things - including asking him to contact Vanessa Lopez and convince her to meet."
Given the new book, "She's scared, not only because she'll be named, but because now Shaq could turn around and sue her for breach of contract."
