Lovebirds caught in the stands! Justin Timberlake and Jessica Biel attended the U.S. Open on Monday, Sept. 9, in New York's Flushing, Queens, and didn't mind sharing a very rare PDA moment while taking in a match between Rafael Nadal and Novak Djokovic

Snuggled up to the "Take Back the Night" singer, Biel, 31, went in for a kiss on the cheek during the men's singles finals, which Nadal eventually ended up winning. The brunette beauty smooched a smiling Timberlake, 32, as the two tried to keep discreet wearing matching black sunglasses.

The sweet PDA moment is an oddity for the couple of nearly six years, who will be celebrating their first wedding anniversary this October. But, perhaps, distance does make the heart grow fonder. The "Total Recall" actress previously watched a game last week without Timberlake, who was promoting his film Runner Runner in London at the time.

One week prior, Biel supported Timberlake after nabbing his Video Vanguard Award at Diddy and Jay Z's VMA after party and the Ciroc Amaretto Launch Event at hotspot PH-D in downtown Manhattan alongside N' Sync members Joey Fatone and Chris Kirkpatrick. "Jessica was amazing. She was having a blast and the guys loved her," an insider told Us Weekly at the time.

"It's nice to marry your best friend. It suits me," Timberlake told Ellen DeGeneres during a talk show appearance in April 2013. "Every once in a while I can catch a glimpse of her when she doesn't see me looking, and I have this moment where I'm like, 'If you never make a good decision…if you only make bad decisions for the rest of your life. You made one really good decision.'"
