Javier & Penelope's Sexy Getaway

The couple that vacations together stays together! Spanish hotties Penelope Cruz and Javier Bardem are apparently still going strong after a recent week-long trip to the super-exclusive Cayo Espanto, a private island resort off the coast of Belize (Tiger Woods is another famous guest.)

The Vicky Cristina Barcelona co-stars kept to themselves, went scuba-diving, had a picnic for two on the beach and used a helicopter to get to and from their excursions.

"They enjoyed their privacy," a source tells OK!.

Although the sizzling twosome have never confirmed their romance, they've been linked since last year. They had tongues wagging even more when they were spotted getting close on a vacation in the Maldives in October. Since then they've been snapped being romantic everywhere from NYC to Nice, cuddling, holding hands and acting like, well, a couple.

While all questions related to their romance were off-limits during press appearances for Woody Allen's Vicky Cristina Barcelona, their offscreen performance as a couple in love seems to be mirroring the white-hot chemistry they share onscreen.

Muy caliente!
