Paris and Nicole to kiss and make up

Paris and Nicole to kiss and make up

Paris Hilton and Nicole Richie are set to publicly end their two-year-old feud as guests of US chat show king David Letterman. The TV host has offered to play peacekeeper after inviting The Simple Life stars to appear together on his Late Show in September. The two former pals fell out amid reports Nicole aired a private viewing of Paris' controversial sex tape. Both girls have refused to go into detail about their bust-up, with Paris repeatedly telling journalists: "She knows what she did."

Paris and Nicole agreed to team up on TV again for the third season of reality show The Simple Life - but refused to work together on-screen.
