Britney Spears' ring from Jason Trawick: Check out the bling!

Britney Spears officially changed her Facebook status to "engaged" on Friday after her longtime boyfriend (and former agent!) Jason Trawick popped the question. How "stars are just like us" of her!
Brit and Jason are spending the weekend in Las Vegas to celebrate not only the new relationship status, but also his 40th birthday -- with a big party, naturally. On Friday night, they celebrated at Planet Hollywood Resort & Casino with friends and family. They also had a celebratory dinner at the Sugar Factory and a dance party at Chateau nightclub.

She showed off her ring for the very first time as photogs snapped pics -- and as is to be expected, it's basically a skating rink. The Neil Lane stunner is a round, three carat stone, with additional pave diamonds on the band.

TMZ says that Jason did the right thing and asked Brit's dad (and, uh, conservator) Jamie Spears for her hand beforehand. TMZ also announced that the couple will be getting a prenup, because TMZ always has their priorities in line.
