The rap mogul and businessman posted a picture of a huge diamond ring on Instagram over the weekend, which TMZ.com claim is his engagement ring for his girlfriend of seven years. Next to the picture of the huge rock he wrote, "Baby do you like it? I just want to get you wat you Like ! I just wanna Mk you smile 😊 #takeDat. ! [sic]."

"It's definitely smiling. Its perfect!" Cassie wrote back. She was later pictured wearing the ring on her engagement finger in a post on the same site by singer Keyshia Cole.

Cassie, 27, is a singer signed to Diddy's Bad Boy records as well as a model who has appeared in campaigns for Calvin Klein, Adidas and Abercrombie & Fitch. She has released two albums, Cassie in 2006 and RockaByeBaby last year.
