Diddy engaged?

Star magazine is reporting that the dad of six is said to have proposed to his girlfriend, singer Cassandra “Cassie” Ventura.

A source tells the mag, “He told everyone to keep it extremely quiet because he didn’t want it to get out, but you could tell he was excited.”

They add, “Diddy said they hadn’t set a date yet, but he wanted his family to hear the news first.”

Diddy met Cassie after signing her up to his label in 2006. She’s also 17 years younger than diddy.

Ummm. . . doesn’t he have like 18 kids with Kim Porter?!? Why didn’t he marry her?!
