Michael Bublé found the ultimate audience for his song Haven’t Met You Yet – a fan’s unborn child.

The singer was appearing on Rachael Ray’s TV chat show in the US, when a pregnant fan sitting in the front row with her husband revealed that her unborn baby constantly hears his music.

“We are major fans – I love you!” said the fan. “We have two little children that are always dancing around to you at home. We sing your songs to our baby all the time.”

Bublé then asked the woman if he could “sing to the baby” and, as she screamed with joy, he bent down to her pregnancy bump and sang Haven’t Met You Yet.

The ecstatic mum-to-be joked: “I’m not supposed to get too excited because I’m pregnant with our third child!”
