Are Diddy and Cassie Engaged?

Is he, or isn't he? Star magazine reported today that Diddy is engaged to singer Cassandra "Cassie" Ventura, but the music mogul's rep denied the reports to People.

A source told Star,"[Diddy] told everyone to keep it extremely quiet because he didn't want it to get out, but you could tell he was excited." The source added that "Diddy said they hadn't set a date yet, but he wanted his family to hear the news first."

According to Star, Diddy revealed his engagement to Cassie, who is 17 years younger and signed to his label Bad Boy Records, at his son Justin's eighth-grade graduation ceremony in New York, on June 5.

But Diddy's mouthpiece says the rumors are false. "Contrary to tabloid reports, there is no engagement. This was a complete fabrication," states his rep.

Cassie told People at DJ Cassidy's birthday bash in New York: "We are not together, but we are definitely friends." Adding, "We work hard together, so it makes a good combo."

Could this all be a publicity stunt to promote one of Diddy's various reality shows, clothing lines, fragrances or up-and-coming artists, or is the rapper/entrepreneur playing coy with the paparazzi until he can break the news of his romance to his ex-girlfriend and mother of three of his five children, Kim Porter? Something tells us this isn't the last we'll hear (or see) of Diddy and Cassie...
