John has had an especially difficult month as he has mourned the passing of his co-star Olivia Newton John.
John posted a lovely flashback photo of the two at what appears to be a movie premiere or party on Instagram to wish Kelly a very happy birthday.
In the picture, they are securely clutched together. The actor is dressed in a black suit with leather lapels, and his wife is wearing a very stylish outfit.
Kelly can be seen beaming broadly while donning a black dress with white piping and cut-outs at the waist, pearl drop earrings, and voluminous beehive-styled blonde hair.
