Chrissy posted this picture along with a sweet message that read, "Another year with you has flown by and I am so proud of what you've accomplished. Every year, I wonder how things can even get better but you always find a way. Happy *37th* birthday to the most wonderful, hard-working, loving being I, and anyone who has ever met you, have ever known. We love you, my handsome old man. Also I'm sorry I thought you were 37 all year," in honor of John's birthday in December 2015.
