Britney Spears and her fiancé Jason Trawick made their debut as an engaged couple at Planet Hollywood in Las Vegas on Friday evening.
"Tonight was one of the most magical nights of my life," Spears, 30, tweeted after the bash, which included a dinner at Sugar Factory American Brasserie and dancing at Chateau nightclub. "Such an amazing time with my new fiancé and our closest friends and family."
Spears wore a pale pink dress as she proudly showed off the three carat Neil Lane sparkler given to her by her former agent beau.
"This is something they've both wanted for a long time," a source explains to Us. "It's a way to cement their family. They're both extremely happy and can't wait to become man and wife."
