Miss Britney Jean Spears turns 28 today - and we couldn't be happier.

She's been entertaining us for more than a decade now, and while there were some dark years in there, the pop princess is back and better than ever.

Not only does she continue to crank out hits and cement her place as one of the most successful recording artists of all time, she seems quite content.

With a strong new man in Jason Trawick (recent rumors aside), and two adorable young sons, it's good to be Britney Spears. We're lucky to have her.

Britney and Jayden James share one of those tender moments.

We just hope Kevin Federline remembers to send his ex-wife a card. His current girlfriend, Victoria Prince, also celebrates her birthday today (she's 27). Irony.
