Amal & George: Rowing On Their 5th Anniversary

Tension flare on their special night out in NYC.

It was meant to be a night of celebration, but Amal and George Clooney looked surprisingly stressed out as they marked five years of marriage.

The couple celebrated their wedding anniversary at 4 Charles Prime Rib in Manhattan with good friends Cindy Crawford and Rande Gerber. But the high profile pair looked downcast as they left their New York home and George put a protective hand out for Amal who, at one point, appeared to be crying.
