Amy Winehouse Saddles Up in St. Lucia

Seemingly unfazed by last week's break-in at her London home, Amy Winehouse is still frolicking in the sun on her extended tropical holiday.

The British songstress, who has been partying in the Caribbean for over a month, saddled up with an unidentified friend in St. Lucia recently. The two were photographed riding along the shore.

The multiple Grammy Award winner, 25, previously had been photographed on the arm of hunky former rugby player Joshua Bowman, prompting her jailed husband Blake Fielder-Civil to commence divorce proceedings against Winehouse over adultery.

Who knows when the vacation will end, but Winehouse is set to headline the Coachella Valley Music & Arts Festival in Indio, Calif., this April with Paul McCartney, the Killers, the Cure and Morrissey.
