Britney's Date Night
Britney & Jason enjoy a romantic date in London.
Britney Spears has got some new bling!

The newly engaged singer, 30, proudly displayed her sparkler while attending her fiance (!) Jason Trawick’s 40th birthday party at Chateau Nightclub in Las Vegas on Friday evening. The couple was all smiles as they snacked on couture lollypops and Jason’s birthday cake.

So, what are the deets on that gorgeous ring?

According to E! Online:

“Neil Lane designed Britney’s engagement ring and according to Lane’s rep, Trawick personally worked with the designer to craft the diamond-bearing band into Spears’ ‘dream ring.'”

Also, the round diamond boasts about four carats and “features micro pave diamonds around the band.”

Simply stunning!

Jason popped the question to Brit on Thursday after about three years of dating.
