George Soros' former girlfriend Adriana Ferreyr says the billionaire reneged on a promise to buy her a New York apartment.

Ferreyr Wednesday filed a $50 million lawsuit against Soros in Manhattan court, according to The Associated Press.

The 28-year-old former Brazilian soap actress claimed that the 80-year-old Soros had said he would give her an Upper East Side apartment worth $1.9 million, but later broke up with her and promised the apartment to another woman.

During a brief reconciliation, Ferreyr said that Soros told her of his plans.

"While still in bed, Soros slapped Ferreyr across the face and proceeded to put his hands around her neck in an attempt to choke her," the lawsuit alleges.

Ferreyr also said that the octogenarian tried to strike her with a glass lamp.

He "denies throwing the lamp and totally denies trying to choke her," an unnamed friend of Soros told The New York Post. "This is about a lot of money and an apartment."

"Mr. Soros did have an on-again, off-again and non-exclusive relationship with Ms. Ferreyr," William Zabel, Soros' lawyer, admitted. "The complaint is riddled with false charges and is obviously an attempt to extract money from my client, who is a very wealthy man."

"The police investigated the... incident referred to and concluded that no assault occurred... George Soros did not slap, choke or throw a lamp at her."

The couple reportedly met in 2006 at a luncheon in the Hamptons.
