Carrie Underwood had an emotional moment during her concert with Keith Urban at The Arena At Gwinnett Center outside of Atlanta on Thursday. During a performance of "Don't Forget to Remember Me," from her album Some Hearts, the country chanteuse broke down into tears in the middle of the song's second chorus. According to an audience member, the singer cried through several lines of the song - then attempted to tackle the chorus but broke down again. According to a rep for Underwood, the emotional song was inspired by the singer's mother - and leaving home. In it, she sings: "Hey Momma ... tell Me-maw that I miss her/ Yeah, I should give her a call/ And make sure you tell Daddy that I'm still his little girl."

According to her rep, "Carrie just got overwhelmed in the moment with the song 'Don't Forget To Remember Me.' When she reflects on what has happened to her in the past few years since Idol, coupled with the crowds' reaction to that song, she just reacts in performance." But the night wasn't all dour for the former Idol. According to a concertgoer, Underwood later perked up, telling the crowd she's found the love of her life. His name? Ace - her dog!
