Britney Spears Celebrates Her Engagement & Flaunts Ring In Vegas

The newly betrothed pop singer went out on the town with her new fiancé to celebrate the happy news!

It was just last week when Britney Spears, 30, ecstatically tweeted her big announcement to the public: "OMG. Last night Jason surprised me with the one gift I've been waiting for. Can't wait to show you! SO SO SO excited!!!! Xxo"

Everyone knew exactly what she meant. Britney Spears Is Engaged To Jason Trawick!

A day later, the couple (and Britney's two children) hopped a plane to Las Vegas to celebrate not just Jason Trawick's 40th birthday, but also their engagement.

According to People, the couple went to Planet Hollywood, where they stayed in one of the most lavish hotel suites—complete with a stunning red Murano glass chandelier, a full dining room, bathroom with jacuzzi tub and a breathtaking view of the Paris Hotel's Eiffel Tower and the iconic Bellagio fountains.

That evening, the couple stepped out for their celebratory festivities (Britney used this opportunity to show off her Neil Lane engagement ring—a 3 carat sparkler!—for the first time). The couple first met with Planet Hollywood Chairman, Robert Earl, for a congratulatory welcome on the hotel's mezzanine, where Trawick was presented with an enormous birthday cake. They made sure to make this event a quick one, as Britney wanted to get back upstairs to tuck her little boys in before they fell asleep.

Once the young ones were nestled in their beds, Britney and Jason went back downstairs to enjoy a light dinner of turkey burgers and club sandwiches (not too fancy) at Sugar Factory's Chocolate Lounge, according to the mag. They followed the dinner with cupcakes and a large ice cream sundae topped with sprinkles.

"Britney seemed happy, holding Jason's hand," an onlooker told People. The couple spent time at a VIP table that overlooked the dance floor earlier in the evening, but they must have taken to their feet soon after, as Spears was reported to have been "dancing up a storm" until the wee hours of the morning.

Britney has been glowing since the engagement. The morning after their Las Vegas celebrations, she took to her Facebook page to write: "Tonight was one of the most magical nights of my life. Such an amazing time with my new fiancé and our closest friends and family."

Cheers to the happy couple!
