Paris HiltonParis Hilton has revealed that her feud with Nicole Richie has gone on for so long because she doesn’t know how to make the first move towards reconciliation.

She said: “Nicole and I are going through something right now, but I love her. She’s like a sister to me, so hopefully we’ll work something out.”

“I’m scared [to call her]. It’s just weird and hard when you haven’t spoken for so long. I don’t know what would happen. I’m going to wait a while.”

“I’ve known her, like, 20 years and the whole thing is ridiculous.”

The pair have both been invited to appear on The Late Show next month with David Letterman agreeing to help them repair their friendship.
