George Soros and Adriana Ferreyr in the Caribbean on Dec. 31, 2010
George Soros' 28-year-old former flame is suing the billionaire over a broken promise to buy her a Lexington Ave. pad -- and now she wants $50 million for her trouble.
Jilted lover Adriana Ferreyr, a Brazilian soap opera star, alleges Soros, 80, gifted the luxe digs to a new sweetheart after they had a falling out around the time of the closing, both sides said.
"This is a blatant attempt to shake down George Soros," said Michael Vachon, a spokesman for the philanthropist and famed investor. "The lawsuit is frivolous and completely without merit."
Meanwhile, a gal pal of the actress countered that Soros swore he would buy his on-again, off-again lovebird a place in the city -- and then reneged after she spent the shoe leather to find it.
"I don't think what he did was fair," said Selma Fonseca, 45. "She did all the leg work finding the place and then he tossed her aside. You don't do that to somebody and especially someone you have been with for five years. It's disrespectful."
The May-December lovebirds, who met at a Manhattan charity soiree, hit the rocks recently over something trivial that quickly mushroomed into a full-fledged "War of the Roses," Fonseca said.
The suit, filed in Manhattan Supreme Court, alleges things got so bad, Soros slapped the Columbia University student during a tiff.
"That is totally untrue and a fabrication," countered Vachon regarding the violence. "This is obviously nothing more than an attempt to extract money from a wealthy man, who has done so much for the community."
Reached Wednesday night, Ferreyr, said, "It's a private matter for me. I'm really busy with my schoolwork and am trying to focus on that."
The suit seeks $50 million in damages, according to a source who has read the complaint.
"It's 1/7000th of his wealth," said Ferreyr's lawyer. "She just wants what he promised her."
