Nicole & Keith Heat Up St. Barts

Before kicking off his Love, Pain and the whole crazy thing world tour next month, Keith Urban turns his full attention to wife Nicole Kidman on Monday during their trip to St. Barts – their first vacation together since Urban's release from rehab in January.

The couple shares a cozy moment over lunch at an outdoor café on Monday. "We've dug really deep," Kidman has said about how she and Urban kept their relationship solid three months into their marriage, when the singer checked into rehab.

A week ago they were hobnobbing with A-list pals at the Oscars, but Urban and Kidman are equally at ease taking a low-key stroll along the waterfront on the French West Indian island on Sunday.

Kidman and Urban bask in the breathtaking views during a boat tour of the island on Sunday. Since his release from rehab in January, Urban has gushed about Kidman's unwavering support. "They say grief makes hearts and closer bonds than joy ever can," Urban told the Today show's Matt Lauer. "We've been through a lot, and she's been extraordinary."
