Carrie Underwood kisses young fan

Underwood, 29, saw a young boy named Chase holding up a poster asking her if she would be his first kiss, reported Contactmusic.

Responding to his request, Underwood asked the boy to come up on stage at the gig in Louisville and said she would fulfil his request.

Underwood joked that her husband Mike Fisher was in the crowd, but then said Chase was the "smartest kid ever" and said she would do it.

After the quick peck on the lips, she said, "That's the only time that is ever going to happen!"
