Singer is thought to be engaged to boyfriend Jason Trawick

Britney Spears is set to marry for the third time, according to reports.

USA Today claim that the ‘Femme Fatale’ star was proposed to by her boyfriend and former agent Jason Trawick yesterday (December 15), the same day as his 40th birthday.

“This is something they’ve both wanted for a long time,” a source said. “It’s a way to cement their family. They’re both extremely happy and can’t wait to become man and wife.”

Spears seemed to hint at the news herself, meanwhile, in a post on her Twitter account. She wrote:

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

Britney Spears has been married twice before. Her first marriage, to childhood friend Jason Alexander in 2004, lasted just 55 hours before it was annulled. Later that year she married dancer Kevin Federline, but the pair split in 2007.

Last year, she and Trawick confirmed that they had ended their business relationship so they could begin a romance together.

Earlier this week (December 15), it was reported that Spears was being sued by her former security firm, with the Advanced Security Concepts Corporation alleging that the singer and her team have failed to pay them an outstanding fee of $141, 623 (£91, 294).
