Aww! Miranda Lambert celebrated boyfriend Anderson East’s birthday with some adorable PDA.

Lambert shared a sweet snap of the couple smooching for East’s 28th birthday on Sunday. “Happy Birthday to my favorite ‘Bama’ boy! @andersoneast #candidkisses #withtheband #tourlove #rolltide #&erson #TexasBama,” she captioned the photo on Instagram.

It was a rare glimpse at the couple, who keep things pretty private on social media.

“I really believe in leaving some mystery,” she told the magazine in May. “I don’t need to know what everybody’s doing all the time – especially with heroes of mine. I want to keep admiring them from afar.”

On Monday afternoon, the singer will release the first single off her upcoming album to country radio. Written by Lambert along with Shane McAnally and Josh Osborne, “Vice” will be available at 3 p.m. EST.
