Britney Spears is getting ENGAGED?

Britney Spears is getting engaged!
For music video purposes, but still.
E! News has learned that the pop star who apparently gets a kick out of people thinking she's on the verge of retying the knot will at least play an engaged gal in her new video for "Criminal," with a big, fancy ring and everything.

But guess who has major objections and doesn't plan to forever hold his peace?

Spears' real-life would-be fiancé boyfriend, Jason Trawick, plays the white knight who saves the day when Brit's make-believe fiancé gets abusive at a party, according to BreatheHeavy.com's Jordan Miller, who obtained a leaked copy of the casting synopsis.
Trawick shows up, punches out the bad dude and then he and Spears, who tosses her ring in the dust, hit the road on a motorcycle and end up on a crime spree.
Wild! (They probably just should have kept the bling and used that for cash, but...hey, that's just us.)
So, when more photos showing Britney wearing a diamond on that finger inevitably make the rounds, remember it's all for show. To think otherwise would be "Criminal."
