Where better for a Disney star and her tween heartthrob boyfriend to celebrate her birthday than the happiest place on earth?

Selena Gomez, who turned 19 on Friday, was treated to a fun day out at Disneyland by her beau Justin Bieber.

The young lovebirds were spotted browsing one of the park's many merchandise stores picking up various items.

The pair even had a staff member following them around ones of the stores, carrying all their selections.
