Miranda Lambert took to Instagram on Monday (7/17) to share a sweet birthday message with her boyfriend, Anderson East. Lambert wrote, "Rock & Roll Sundays and No Makeup Mondays. My favorite Bama boy turned 30 today. He owns the stage and he owns my heart." The message came a day after Miranda sang Anderson "Happy Birthday" onstage as he opened for Chris Stapleton. In her message, Miranda also thanked East for inspiring her in so many ways and said, "You are a light that could outshine the sun. I love making memories with you."
