Britney may have been the last to know about the announcement of her breakup with ex-fiance Jason Trawick.

“It really wasn’t Britney’s decision to announce the split last week, it was Jamie who made the call,” a source tells RadarOnline.com.

“Jason wanted out, and in the fragile state that Britney is in, it’s not like he could have a rational conversation with her about it, so it was really between him and Jamie. They decided how the relationship needed to end and how to go about the technicalities, such as removing Jason from the conservatorship, when he would move out and how to announce the split. Britney was left out of everything and really didn’t even know what was going on.”

When it came time to tell Britney about the now public news, the source claims Jason and Jamie sat her down in a safe and controlled environment and carefully explained the situation because they feared she wouldn’t take the news well.

“Jason and Jamie wanted to make sure that Britney didn’t lose it, so they had to water things down for her a bit,” the source says.

“She knows that the engagement is off and that Jason has been removed from the conservatorship, but she still hasn’t exactly grasped yet that the relationship is totally over.”
