Los Angeles, Calif.-The heiress is single again.

Paris Hilton and boyfriend Doug Reinhardt have apparently called it quits.

“In response to the inquiry on whether Paris Hilton has split up with Doug Reinhardt, yes, this is true they are no longer together,” says a rep of Hilton. “They remain friends and ask that you please respect their privacy.”

The news of their breakup surfaced as the celebutante went off to Dubai in search of a new best friend on the latest season of her reality show “Paris Hilton’s My New BFF,” which was previously based in Los Angeles and London.

According to reports from the Associated Press last week, Reinhardt was supposed to join Hilton on her trip. The couple were totally inseparable for the whole six months of their relationship, and were last spotted together at the Cannes Film Festival for the screening of Hilton’s documentary, “Paris, Not France.”
