Michael Buble sings to his newborn son to get him to sleep.

The 'Haven't Met You Yet' crooner welcomed a baby boy named Noah with wife Luisana Lopilato on August 27, and he is already serenading the little tot using his famous vocal chords.

In an interview with Canadian talk show 'The Social', he said: "I sing to him all day and all night. When he's crying with somebody else and I hold him and I sing to him, he just stops. It's really cool.

However, the 37-year-old singer admits he hasn't been singing his own songs to baby Noah, instead opting for soothing nursery rhymes.

He added: "The songs I'm singing are not my hits, that's for sure. My number one go-to right now is 'Down by the Bay.' "

Michael is loving fatherhood and says the birth of his son is the "greatest thing that could ever happen".

He gushed: "You can't explain it until it happens; it's like telling somebody what water feels like before they've ever swam in it."

While he may be enchanted by Noah now, the Grammy Award-winning star reveals that he wasn't immediately overcome with emotion during his son's birth.

He admitted: "I didn't have that overwhelming feeling of love. I'm being honest with you. I'd heard all of these stories about how this moment was life-changing, but it wasn't like that for me. I was nervous for my wife and I was happy that he was healthy, but that day, it was like meeting a stranger. I think that next night, it really clicked. I was looking at him, and all of a sudden, I got it."
