Britney Spears shared a personal snap on Facebook last night. She modeled the new engagement ring given to her by fiancé Jason Trawick and captioned the snap, "I can't stop looking at it!" Britney and Jason got engaged just before Christmas and headed to Las Vegas for a bash that doubled as a congratulations party and a celebration for his 40th. They spent the holidays together and ventured away from LA for a quick trip to NYC. We'll see if the next 12 months include a wedding for Brit and Jason, or even an expansion of their family! One of our favorite 2012 celebrity predictions is a baby girl for Britney, who's already the mother to her two sons, Sean Preston and Jayden James.
