R+B star Cassie is unfazed by reports she is dating her hip-hop mentor Sean Combs. The 38-year-old rap mogul was rumoured to be romantically involved with the singer, 21, after he signed her to his Bad Boy record label in 2006. And despite protestations from Combs last month (Dec07) denying the relationship, Cassie insists she isn't worried about the allegations they are a couple. She says, "I'm his artist and we're friends. It doesn't bother me if people say we're dating. I'm like, whatever."
