It looks like Britney may settle down with the right guy this time. The pop star is engaged to her former manager and longtime beau Jason Trawick, who popped the question Thursday night. "This is something they've both wanted for a long time," a source told Us Weekly. Clearly thrilled, Spears hinted at the news on Twitter 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!!!!" The couple met in 2006, before she split from then-husband Kevin Federline, the father of her sons, Sean Preston and Jayden. Trawick was a supportive friend to Spears throughout her personal struggles in 2007 and 2008. In 2009, they took their friendship to the next level. "He makes me laugh, and we are so comfortable being ourselves," Spears told Us earlier this year.
