(contactmusic.com) - Hip-hop mogul P.Diddy (Sean Combs) has reportedly quit his womanising ways to revive his relationship with ex-girlfriend 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), but the couple appear to be back together. A source tells New York Post gossip column PageSix that Combs has made the decision to "cut off the various girls he has around the world" and settle down with Cassie. The insider adds, "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."
