In the snapshot posted to Megan's grid, MGK and the actress twinned in coordinating trucker hats as he gave her a cute piggyback ride. Megan's featured a hot pink "C" (likely for Colson) on the front, while Kelly's was the same color as his pastel pink hair. He paired the hat with light-wash jeans and a studded T-shirt, and Megan, for her part, wore a black leather jacket, ripped denim, and the tallest platform boudoir heels.
"Today your mom told us that you were born a month early (you were SO meant to be a Gemini, you charming mercurial Svengali) and as a baby you were both 'cuddly and fussy at the same time' and I couldn't have imagined a more apt description of you," Megan began her birthday tribute. "The world has no idea what a gentle, beautiful heart you have. How generous and how thoughtful you are…How absurdly strange and smart and witty you are…You are by far the most unique human I have ever met."
She continued her caption with one of the most heartwarming sentiments ever, "And if I could get the boy who has everything something special for his birthday - I would lift the veil off of their eyes so they could see what I see. You're such a gorgeous soul." Megan added, "I'm honored to love you and to be the recipient of your love. Happy Birthday love of my life ❤️🩹."
MGK shared his own birthday post that comprised of images from his celebration — including face masks with his 12-year-old daughter, Casie, a new tattoo, and a sing-along session with his and Megan's cat, Whiskey, to his song "Make Up Sex."
