Rhett's wife, Lauren Akins, also used Instagram to express her gratitude for her daughter, whom she met while on a service trip in Uganda. Akins also reiterated Willa's selflessness and said the 5-year-old is \"the easiest person to celebrate.\"

\"Willa Gray I say this all the time but I mean it: you are full of magic baby!\" she wrote. \"I’m so happy our souls found each other because I wouldn’t be complete without you. Happy birthday precious girl.\"

The couple brought Willa home from Uganda in 2017 after a year-long adoption process. That same year, they welcomed their second daughter, Ada, followed by Lennon in 2020.
