Paris Hilton and Doug Reinhardt have called it quits for the second time in less than a year.

"The relationship between Paris and Doug is over," Hilton's rep said in a statement. "She broke up with him more than two weeks ago."

Hilton, 29, and the 24-year-old Hills star started dating early last year and split in June before reconciling.

Hilton reportedly partied with Kim Kardashian's ex, Reggie Bush, at a Las Vegas club over the weekend, but the socialite tweeted that she and Bush never communicated.

Is Reggie Bush spending time with Paris Hilton?

"Aside from being @ the same club, Reggie and I didn't even say hi to each other. I was there with my sister and friends," she wrote.

Calls and e-mails to Reinhardt's rep were not immediately returned.
