Diddy and Cassie Ventura: Engaged!

The news that Amy Adams was engaged to Darren Legallo wasn't met with much excitement this morning.

But celebrity gossip followers are abuzz with this wedding news: Diddy is set to marry Cassie Ventura!

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

The hip-hop mogul met the 21-year old Cassie when he signed her up to his label, Bad Boy Records, in 2006.

About a year ago, Diddy ended his 10-year relationship with Kim Porter, the mother of his twins.
