Paris Hilton: Single or Back on With Ex?

Paris Hilton is single again after fourteen months with Doug Reinhardt — or is she? The socialite gave sightly mixed signals during her Friday appearance on the Ellen DeGeneres Show.

"I'm just enjoying being single," she told Ellen DeGeneres. "I swear I haven't gone on any dates."

After DeGeneres pressed further, she admitted, "I had one…last week."

The lucky guy was "someone I was with for like years back in the day," whose name is "Jason," she added.

One notable Jason in Paris' past: model Jason Shaw, to whom she was once engaged before calling it quits in early 2003.

"I love him so much," she admitted. "We're very close and I've known him a very long time."

In mid-April, Hilton's rep confirmed that the star had split with Reinhardt, 25. And Hilton told UsMagazine.com last week: "I am like so past that — I don't even care! I don't even remember that time in my life."

Fond memories of Hills star Reinhardt? Not so much, she told Us. "I'm better off without him…He wasn't right for me and I will eventually find somebody who loves me for who I am."
