LONDON: Rapper Sean Combs is planning to marry singer Cassie, who is 18 years younger than him. According to contactmusic.com, Diddy, 39, has asked the 21-year-old R&B star, whose real name is Cassandra Ventura, to be his wife. A source said Diddy talked about his marriage plans at his son Justin’s recent eighth grade graduation party.

“He told everyone to keep it extremely quiet because he didn’t want it to get out,” said an insider. Diddy first met Cassie when he signed her to his Bad Boy Records label two years ago.
