Can you guess who was spotted showing off her 6 carot diamond engagment ring recently?

Hint: “Love don’t cost a thing” but from the looks of this rock it costs plenty…

I know you know. I just wanted an excuse to post that movie poster… 😆

Yes…. it’s none other than Christina Milian!

She and her boo, The Dream were spotted at Billy Clark’s Birthday celebration in Hollywood las weekend color coordinated and cute. Her toned down hair color combo is oh so flattering.

I was skeptical at first but now I’m really starting to believe in these two!
