Selena Gomez, Justin Bieber: Beach Couple Vacations In Mexico (PHOTOS)

Talk about striking a pose. Selena Gomez and Justin Bieber soaked up the sun in Mexico -- they were in the country to attend a wedding -- and got quite cozy during some downtime on the beach.

Gomez rocked a tiny blue bikini while Bieber lounged shirtless, in denim shorts, snapping photos of his beautiful sunbathing girlfriend while she relaxed.

Summer love in December? These are two lucky kids.
