The hotel heiress allegedly grew paranoid when her Greek shipping heir boyfriend conversed with a friend in his native language without including her, during a recent night out at the Roosevelt Hotel in Los Angeles.
A source tells gossip site The Scoop, "Stavros was with a Greek friend, and Paris was freaking out because she couldn't understand what they were saying.
"She thought they were laughing at her."
Hilton reportedly exploded with rage when Stavros subsequently failed to comfort her for looking upset.
The insider adds, "Paris has never seemed so upset. She really thought that Stavros was the one."
