Is Britney Spears Soon To Be Engaged?

After a prolonged stretch of apparent sanity, it looks like Britney Spears may soon once more walk down the aisle.

According to RadarOnline, boyfriend Jason Trawick has been a busy man. If diamonds are girl's best friend, then let's call him a good "friend of a friend": he's apparently been browsing Tiffany and Harry Winston selections looking for just the right rock to talk the pop icon into a third try at wedded bliss.

The blog claims he's currently keeping his main squeeze company on the South American leg of her ongoing Femme Fatale Tour, but is near a decision. In a move that's somewhat uncharacteristic when it comes to celebrity engagements, he's actually leaning toward a somewhat low-key bauble.

“Don’t expect anything too massive or obnoxious.  This ring will be classy and under four carats," a source reportedly close to the pair said.

For what it's worth, that makes the second source that's told RadarOnline another Spears engagement draws near.

“Britney and Jason discuss marriage all the time,” a source told the blog last week. “Britney is truly in love with Jason, and well, Jason has loved her for a very, very long time."

Spears turns 30 Dec. 2, and first tested matrimony's waters with a 55-hour-long marriage to childhood friend Jason Alexander. Her marriage to Kevin Federline lasted three years from 2004-2007, produced two children and the bizarre reality series "Britney & Kevin: Chaotic" and ended with a custody battle between the two centered often on Federline's accusations of Spears' frequent drug and alcohol abuse.

Spears and Trawick, 39, have been together since 2009.
