The pop star's beau of three years, Jason Trawick, 39, has reportedly already bought the ring. A source tells the mag:

    "Theyve been talking about marriage for a long time. It would be surprising if they are not engaged by the end of the year."

Following the incredible success of her Femme Fatale tour, this would be the cherry on top for Ms. Spears. As for turning a year older, the source adds:

    "Britney is really looking forward to turning 30. She is having one of the best times of her life."

You go, girl!
