Britney Spears is still floating on cloud nine, three weeks after her engagement to boyfriend Jason Trawick.

On Wednesday night, the 30-year-old pop princess posted a new photo of her engagement ring on her official Tumblr page.

I can't stop looking at it!! Spears wrote.

Although the photo barely does the sparkly engagement ring justice, Spears' smile says it all.

On Dec. 15, Trawick popped the question during the couple's outing in Los Angeles.

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, Spears wrote on Twitter at the time.

A source revealed to People Magazine that Trawick, 40, surprised Spears after she gave him birthday gifts. He reportedly proposed with a 3-carat Neil Lane diamond.

The pair continued their engagement celebrations in Las Vegas later that week, complete with a second birthday party for Trawick at Chateau Night Club.

Still Glowing . . . 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. #Blessed, Spears declared on Twitter.

Spears and Trawick, her former agent, spent the holidays in New York City, hitting hot spots including The Darby. The two reportedly shared an intimate dinner in a private booth, as the restaurant's band serenated the newly engaged couple with a cover of Spears' hit single, Toxic.

Spears is fresh off the heels of her Femme Fatale world tour, which ended in December. Her seventh studio album of the same name debuted at number one and became the former Mouseketeer's first album to produce three top 10 hits on the U.S. Billboard Hot 100 chart.

Before Trawick, Spears was married to Kevin Federline for three years, until their 2007 divorce. Spears and Federline have two sons - Preston, 6, and Jayden James, 5. Spears was also previously married to childhood friend Jason Alexander. Their Las Vegas nuptials were annulled 55 hours later.

Spears and Trawick, who have been dating since 2009, have yet to announce their wedding date.
