It seems that the myth that married couples start to look alike after time may be true...and in the case of Kaley Cuoco-Sweeting and Ryan Sweeting, it may not even take that much time.

The affectionate lovebirds, who tied the knot on New Year's Eve, sported nearly matching outfits as they walked arm-in-arm while out for a lunch date. The Big Bang Theory star kept it very casual and wore an oversized gray tee and black plants. She accessorized her low-key look with a visor, dark sunglasses and orange flip flops.

Meanwhile, her tennis pro hubby donned a similar color scheme, in a Nike shirt, black athletic shorts and bright red sneakers.

This isn't the first time the PDA-friendly pair has decided to dress alike. The newlyweds teamed up for a charity tennis match back in March and rocked cute coordinating pink ensembles on the court.

The 28-year-old blonde shared a pic of the duo embracing at the event on Instagram. "Had a blast playing a little mixed with @ryansweething tonight. A man who agrees to wear pink, is a very, very good man :)," she wrote.

Perhaps the pair are hoping to create a new rule: The couple that coordinates is for keeps.
