Nicky Hilton and Kevin Connolly have split after two years of dating, according to reports from People and Us Weekly magazines.
"They're no longer a couple," Hilton's rep confirms to Us Weekly.
Hilton, 23, younger sister to Paris, and Connolly, 32, a regular on HBO's hit show "Entourage," began dating shortly after she annulled her quicky Vegas marriage to businessman Todd Meister.
A Hilton pal told Us Weekly the heiress "dumped" Connolly on Oct. 16 after she suspected he had cheated.
One celebrity blog reported that Connolly hooked up with Brittany Field — 18-year-old daughter of music mogul Ted Field — when Nicky was in New York for fashion week last month.
