Babes on board!

Jennifer Aniston and Justin Theroux continued their romantic European tour with a sexy five-day vacation to Capri and spent time relaxing together in the sun.

The couple arrived on June 17 to the JK Place hotel in Marina Grande and rarely even left their $3,750-a-night room, except for a boat tour on June 19. Aniston, 43, and Theroux, 40, flaunted their toned torsos on the deck of the Liberty of Lymington, which rents for $17,555 a week.

The entire getaway was dreamed up by Aniston, says a Theroux insider, "to take Justin to some of her favorite places." They began their sojourn in Paris on June 10, following by a few days in Rome.

"She and Justin are extremely happy with where they are right now," says a confidant of the actress, "and in it for the long haul."

And their relationship is thriving, says the confidant, "because they want the same things."
