Britney Spears and Jason Trawick.

Britney Spears will be walking down the aisle again. Jason Trawick, the pop star's former manager and boyfriend of more than a year, confirmed to " Access Hollywood" today that he proposed to Spears on Thursday.

"Yes, we are engaged," Trawick said, saying he's "over the moon" and so is Spears.

Who is Britney Spears' new man, Jason Trawick?

Trawick told "Access" that he got down on one knee to pop the question and Spears' sons,  Sean Preston, 6, and Jayden James, 5, witnessed the happy proposal.

The singer hinted at the news in a  tweet this morning: "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"

According to Us Weekly, Spears had been expecting the engagement.

"This is something they've both wanted for a long time," a source told the magazine. "It's a way to cement their family. They're both extremely happy and can't wait to become man and wife."

Spears turned 30 earlier this month. (Trawick is 40.) At the time, People magazine reported that Spears "really wants to get married and have another baby."

As for whether this marriage would be more successful that her first two, which ended in annulment (Jason Alexander) and divorce (Kevin Federline),  the man who directed Britney and Trawick in her "Criminal" music video, Chris Marrs Piliero, told People that Spears' relationship with Trawick appears to be healthy and happy.

"He's chill and cool, which goes well with Britney - she's the same," he said. "They have a solid chemistry and a real bond and trust."
