Paris Hilton and Benji Madden decided to split up

In her last interview guesting in David Letterman show, Paris said that she's in love with Benji Madden.

After 9 months of dating and fun, Paris Hilton and Benji Madden called it quits. According to a close friend of Paris via PEOPLE, "She is saddened by the breakup but they're just too different and they wanted different things in life."

"Even though they are still in love, they felt it would be better to just be friends."

Paris' friends also denies that the reason of the breakup is because of Paris Hilton was seen with ex Stavros Niarchos together this past weekend in Miami.

Benjie is the reason why Paris Hilton becomes tame with her ways.
