Nicole Ritchie trying to keep pal Paris Hilton's ex away from other girls

New York, Nov 28 : It looks like Nicole Ritchie is finding it hard to accept that Benji Madden and her best pal Paris Hilton have parted ways.

According to sources, ever since Madden split from Hilton, Ritchie "has been really possessive and stops him from talking to other girls."

Richie, who has a baby with Benji's twin, Joel Madden, was spotted at a party for the Maddens' band, Good Charlotte, and their latest album, "Greatest Remixes."

"Benji was approached by dozens of ladies. Girls were trying to flirt with him . . . but Nicole kept getting in the way," the New York Post quoted a source, as saying.

The source added that Richie "stopped every girl trying to take a photo of him," and even "dragged him by the arm" away from a busty blonde.
