Public displays of affection among country love birds are becoming commonplace these days, but none were more public than the recent make-out moment between Keith Urban and Nicole Kidman…

Keith probably didn’t expect he’d be laying a  big wet one on wife Nicole when the pair ventured out to the U.S. Open match between tennis great Andy Roddick and Bernard Tomic, who hails from Keith and Nicole’s home country of Australia.

The operator of the “kiss cam” spotted the celebrity couple on the front row and didn’t miss the smooching between the two”¦ in front of a sold-out crowd of 37,000.

Keith and Nicole, who’ve been married for six years now, left daughters Sunday Rose and Faith Margaret behind for their tennis night out.
