Adriana Ferreyr, the bombshell Brazilian ex-girlfriend of billionaire George Soros, says she has her own bomb to drop. In court papers filed yesterday she says she has “recorded conversations” with Soros, as well as with his reps, which support her claim he reneged on a promise to buy her a $1.9 million apartment. Sources say the taped conversations with Soros are “highly personal in nature.” The court papers claim Soros’ own representatives told Ferreyr, “What George had done does seem very cruel and arbitrary,” and that they were “sympathetic to [her] situation and did not know why George was being so stubborn about the apartment.” Ferreyr also says, “George hired security personnel to stalk and follow me on a daily basis, to attempt to scare me,” and she had to be treated for “extreme anxiety.” Soros’ lawyer, William Zabel, said of the claim about the recordings, “When I first met with [Ferreyr] she was nearly hysterical, and I tried to calm her. There remains no legal merit to her case.”
