Underwood's concert tears?

Country star Carrie Underwood broke down in tears onstage in Atlanta, Georgia on Thursday while performing a song inspired by her mother.

The 'American Idol' star began sobbing during a rendition of 'Don't Forget to Remember Me', on the latest leg of her tour supporting Keith Urban.

Audience members tell People.com that Underwood struggled through the song, but couldn't overcome her tears.

A representative for the star insists the song was written for her mother, and about her leaving home. Lyrics include: "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."

Underwood later recovered and finished the concert tear-free.
