Nicole and Keith Suck Face in St. Bart's

He might be sober, but Keith Urban still found something to wrap his lips around over the weekend... his wife Nicole Kidman!

Like two high school kids, the kissing couple were caught lip locking everywhere they could during a holiday in St. Bart's. Snog spots included a boat, the ocean and a restaurant.

Just like her ex-hubby Tom Cruise, it seems Nicole can't get enough of the PDA these days.
