SO SICK singer Ne-Yo knew he'd become a big star when Beyonce Knowles dragged him onto the dancefloor at a party just so she could sing along to his hit. The R+B sensation was thrilled when he was invited to rap mogul SHAWN 'JAY-Z' CARTER's birthday party and couldn't believe his luck when the DJ played his huge hit - and that was just the beginning of an amazing night. He recalls, "The song came on and Beyonce was, like, so happy. "Everybody was kind of dancing in the circle, and, like, the crowd kind of surrounded me and her, and she sang my song to me... That was such an honour." And Knowles isn't his only superstar fan - Natalie Cole and Diana Ross are both So Sick lovers.
