IT’S OFFICIAL: PARIS HILTON AND BENJI MADDEN ARE OVER

It's all over between Paris Hilton and boyfriend Benji Madden, Life & Style reports. "Sadly, it's true," Vanessa Fontana, a contestant on Paris' BFF show, confirms exclusively to Life & Style. "Paris and Benji have split. I love Paris, and I just want her to be happy. I think that they'll be better as friends."

Vanessa disputed rumors that the split had anything to do with Paris' brief reunion with ex Stavros Niarchos this past weekend in Miami. "No, nobody else is involved," she says. "Paris and Benji were loyal and faithful to each other. I was with Paris in Miami, and Stavros came over to our table, and the two of them talked for literally two minutes. It was a friendly conversation. They definitely did not hook up."

Sources say the breakup is due to the basic differences in the couple: Benji is a quiet homebody, while Paris is very social, both personally and professionally. And in recent weeks, the strain was beginning to show. "All of Paris' friends have noticed that she hasn't been happy lately," says a friend. "Benji told Paris he didn't like the BFFs from her show, and that he disapproves of her friends and doesn't get along with her sister."

Their work schedules have not helped: Paris regularly travels the world, and is booked with back-to-back projects for the next 12 months, while Benji is currently in the recording studio working on a new Good Charlotte album with his twin, Joel.

Paris is said to be devastated by the breakup. "She wishes it could be different," says the friend. "Benji always treated her like his princess. He's a really great guy with a big heart and she loves him very much. Maybe at some point in the future, the two of them could try again, but right now, they're just too different as people."
