Watch: Miranda Lambert Serenades Husband Brendan McLoughlin With New 'Choosin' Texas' Lyrics

Miranda Lambert playfully serenaded her husband, Brendan McLoughlin, with new lyrics to "Choosin' Texas" to celebrate his birthday.

Lambert, 42, shared a tribute to her husband on Instagram on Wednesday (October 14). The last slide is a clip of McLoughlin getting ready in front of a mirror while Lambert laughs and sings, "He's in Vegas, I can tell by the way he wants to leave the room/ And judgin' by the smile that written on his face, he's got a lot to lose/ Oh no, it doesn't take a crystal ball to see/ Brendan's gonna gamble until he's / Drinkin' Jack all by himself/ He's in Vegas I can tell."

Lambert co-wrote the history-making single with singer Ella Langley, plus Luke Dick and Joybeth Taylor. Her post celebrating McLoughlin's birthday also includes a snapshot of her husband sitting poolside, a photo of him fishing, a glimpse of him helping replace the laces in the country star's shoes, and more. She wrote in her caption, "Happy Birthday [Brendan McLoughlin], 35 looks good on you! Well everything looks good on you but that smile is my favorite ! I love you!"

Lambert and McLoughlin met in November 2018. She and her band, Pistol Annies, were performing on Good Morning America. McLoughlin, a former New York City police officer, was working security. The couple quietly said "I do" in an intimate wedding on January 26, 2019, outside of Nashville, Tennessee. The Crisco artist revealed she and McLoughlin got married on Valentine's Day that year, when she posted wedding photos for the first time. She said at the time that she "met the love of my life," and "my heart is full."
