Actress Paris Hilton was branded by one of ex-fiancée Paris Latsis's pals as a 'hooker', after she declared she has earned her engagement ring and she would not return it to Latsis, now that their three-month engagement is over.

Hilton, 24, dumped Latsis earlier this month, declaring she's not ready to marry. "I feel I'm just not ready for marriage. I have seen the break ups between people who love each other and rush into getting married too quickly - and I do not want to make that mistake".

And, during the weekend, Paris said she will not return the engagement ring. She is quoted as saying: "Paris says I can keep the engagement ring. He says I earned it."

One of Latsis's pals, infuriated by her remarks, slammed the actress, calling her a 'hooker'. He told America's Us Weekly magazine: "How did she earn it? With sex. Like a hooker. It's a diss."

Meanwhile, the famous hotel heiress is said to have already put an eye on another Greek millionaire.

Paris, 24, was spotted at Los Angeles Spider Club on Friday night, making out with Marie-Kate Olsen's ex-boyfriend, Stavros Niarchos, 20, whose family has an estimated fortune of $7.5billion.

A source told America's New York Post newspaper: "They made out all night." The next night, the couple was spotted partying at Element with Paris' sister, Nicky.

An eyewitness revealed: "Paris tried to get the club to turn the lights down so no one could see her and Stavros make out."
