Czech model Petra Nemcova has hit back at reports that she has left Beautiful singer James Blunt and taken up with hip-hop mogul Russell Simmons. Media reports claimed the model and the Def Jam records founder were getting cozy at a CD release party for John Legend and they were reportedly spotted again leaving the JoonBug Masquerade Ball on Hallowe'en night (31OCT06) hand-in-hand. Russell, 49, who is estranged from designer wife Kimora Lee Simmons, claims the pair are just friends. Nemcova lashes out at the reports, telling American publication Us Weekly, "There is nothing truthful about it. I am with James, happy and in love."
