Is Diddy off the market? Has he finally put a ring on it, the "it" being the ring finger of his longtime girlfriend Cassie Ventura, who is also a musician?

Diddy, 44, posted a pic of a monstrous engagement ring that looks to be worth more than most average people's houses on Instagram. He captioned it: "Baby do you like it? I just want to get you wat you Like ! I just wanna Mk you smile :) #takeDat.!"

Shine bright like a diamond below. If that doesn't make Cassie, 27, smile, then nothing else will.

Then, Keyshia Cole posted a pic of Cassie, who appeared to be wearing the ring.

Cassie herself also posted a pic of herself and her man, who first started dating back in 2007. She looks to be wearing that same rock.

Despite all the photographic evidence to the contrary, a rep for Diddy said that he and Cassie "are not engaged."

Ah, okay, so Diddy just gives out diamond rings that look engagement rocks for fun! Sorry, our bad. Still, Cassie Combs just rolls off the tongue, doesn't it?

BTW, need some evidence of Cassie's hotness? Go here. That should be enough to reverse his position on marriage, since in the past, he has said he hasn't been ready to wed.
