The post shows the pair enjoying Darien Lake Theme Park in New York, about to share a kiss while taking a stroll and East being presented with a birthday cake.
“My favorite Bama boy turned 30 today,” wrote Lambert, who was previously married to Blake Shelton. “He owns the stage and he owns my heart. ?Thanks @andersoneast for inspiring me in so many ways. You are a light that could outshine the sun. I love making memories with you.”
Fellow musician East also posted a romantic pic of the couple, thanking fans for their birthday wishes and expressing his gratitude for everything he has.
“I can't believe that I get the privilege to live the life that I get to live,” East wrote. “I have the love of an amazing & kind woman, I get to play music that I love & trust & I get to do it with the greatest band & crew ever & I have the love & support of my family.”
“I love being alive,” he continued. “I love having beautiful memories & I am beyond excited about what the future may hold. Thank you all for everything. I love everything and everyone.”
