Britney Spears is Engaged!

Britney Spears has a lot to be happy about this holiday season! The singer and mom to Preston, 6, and Jayden, 5, is now rumoured to be engaged to longtime boyfriend Jason Trawick.

Jason Trawick, who is Britney Spears’ former manager, popped the question at his 40th birthday celebration on Thursday night. Britney Spears tweeted a hint-inducing tweet early Friday morning, saying that Jason surprised her with the one gift she’s been “waiting for.” The pair began dating in 2009.

“He surprised her after she gave him his gifts and after they had cake last night,” a source told PEOPLE.

Britney Spears, who turned 30 earlier this month, was famously married to high school friend Jason Alexander for 55 hours before marrying backup dancer Kevin Federline, whom she has her two children with.

Jason Trawick is rumoured to have given Britney Spears a Neil Lane diamond.

“She’s very happy. It’s going to be a great weekend,” says another source.

We wonder if another lil’ Britney will soon be on the way?!

Congrats to the lovely couple!
