Sean "Diddy" Combs is giving marriage a chance. The bachelor father of six is quietly telling close friends and family that he and singer Cassandra "Cassie" Ventura are heading to the chapel. "He told everyone to keep it extremely quiet because he didn't want it to get out, but you could tell he was excited," says a source. "Diddy said they hadn't set a date yet, but he wanted his family to hear the news first." Diddy revealed his engagement to the Connecticut native at his son Justin's eighth-grade graduation ceremony in Riverdale, N.Y., on June 5. The hip-hop megastar met 17-years-younger Cassie after signing her up to his label, Bad Boy Records, in 2006. Diddy ended his 10-year relationship with model Kim Porter last July. Do you think Diddy and Cassie make a good couple?
