According to Carson, the country star took his advice and serenaded the No Doubt frontwoman.
“At the wedding, Gwen starts, and she wrote this, ‘Since I was a little girl…’ And she crushes, not a dry eye in the church… It was so perfect,” Carson revealed on Today. “I said to Blake when she was done, ‘Top that, buddy.’ And Blake starts by saying, ‘Gwen’s always giving me a hard time about not writing enough songs, so I wrote a song.’ … Guitar comes in frame, stool, next thing you know, he wrote her a song. He sings her a song while he’s crying that he wrote specifically for her…Not a dry eye in the house.”
