Miranda Lambert shocked the crowd last night by coming up on stage a couple of times throughout the night at Chris Stapleton's 'All American Road Show' in Buffalo.

Lambert was out in the crowd for a brief moment watching boyfriend Anderson East's set before Stapleton at Darien Lake before catching him off guard and jumping up on the stage to sing happy birthday to him with the crowd.

Later on, Miranda came out with Chris Stapleton and his wife Morgane to do 'Fire Away'. It was certainly a treat of a night for Buffalo.
