Miranda Lambert has one loving partner in Brendan McLoughlin! The "Bluebird" songstress turned 37 this week, and her husband of nearly two years celebrated her special day with the most swoon-worthy Instagram tribute. "The list is endless of all the reasons why I love you, but there’s one that holds a special place,” he wrote in part. “It is how you stay true to who you are. No matter what hurdles life has thrown in the way, you have always stayed true to your heart and that says more than you will ever know.”
