LATEST: Hip-hop mogul Sean Combs has denied reports he is dating his R+B protege Cassie. The 38-year-old star was rumoured to have been dating the singer, 21, after he signed her to his Bad Boy record label last year (06), with the New York Post reporting on Monday (10Dec07) the pair were back together. A source told, "She recently broke up with her boyfriend, and they're in Miami together now. They're holed up together in Miami, very low-key. He's really in love with her." But Combs insists the rumours are false, telling blogger Perez Hilton, "I am still single and am not in love with anyone." Combs' publicist confirms the star is in Miami, but is working with all of his artists, not just Cassie, "around the clock constantly".
