Britney Spears Tells Us About "Best Birthday of My Life!"

What scandal? Days after Star magazine and Radaronline published fake reports about Jason Trawick's alleged physical abuse of girlfriend Britney Spears, the content pop singer and her beau of nearly two years were a world away from Hollywood: at a private, $5,000 per-night villa in Conchas Chinas, Mexico, as revealed in the new Us Weekly, out now.

The occasion? Spears' 29th birthday Dec. 2 -- and her former agent Trawick, 39, surprised the singer with a red-velvet cake shipped from L.A. and much more.

The happy duo shrugged off the false abuse rumor for their luxe Puerta Vallarta trip. "They did not allow it to get them down," an insider tells Us.

In fact, Spears tells Us exclusively: "My birthday weekend away with Jason was amazing. Best birthday of my life!"
