Paris Hilton has put her feud with her The Simple Life co-star Nicole Richie firmly behind her, insisting they are "friends forever now". The childhood pals mysteriously fell out in January 2005 after a life-long friendship, but they made up after holding a reconciliation dinner in Los Angeles in October (06), and Hilton insists their reunion is permanent. She gushes, "We've been friends for 23 years of our lives and when you've known someone that long she's like a sister. I'm really happy to have her back in my life. I love her to death! We're definitely friends forever now." "She's amazing. Nicole has a great personality, she's beautiful and sweet, and she's fun to hang out with. She's hysterical - she can make me laugh so hard!"
