Thinking Out Loud

Today, I will discuss about a song from Ed Sheran, Thinking Out Loud. Well, if I'm not mistaken, he became famous from this song. And almost every people fall in love with his single. But, if you listen carefully, you will hear a baby sings with him in ",,,,,an baby my heart (heart) will still fall as hard at 23". That "heart" words spoken two times. Is it creepy? Or do you think it's funny? It's up to you whether if you want to believe what I'm saying or not. If you don't believe me, listen the song and repeat it until you hear it.
