Will the 3rd time be a charm for Britney?

According to a report from Radar Britney Spears’ man Jason Trawick is on the hunt for an engagement ring. A source stated that Brit-Brit’s long time boyfriend has been partaking in some serious ring shopping and plans on dropping some bank very soon for just the right diamond.

Jason is currently on the road with Spears during the South American leg of her Femme Fatale world tour. The source added that Trawick has been careful in his selection of the perfect bling for his Miss Thang.

“He has been everywhere from Tiffany to Harry Winston looking for a ring and he is close to making his final decision. Don’t expect anything too massive or obnoxious.  This ring will be classy and under 4-carats.”

Britney turns 30 (wow – Britney Spears will be 30) on Dec. 2nd. Trawick is 39 and the two have been an item since 2009.

This would be Britney’s 3rd marriage if this report is accurate and if she says, “yes,” of course. She was hitched to childhood pal Jason Alexander for 55 hours and then later married K-Fed which ended in divorce after 3-years in 2007.
