Canadian singer Michael Bublé, 37, is expecting his first child with wife Luisana Lopilato, 25, but this exciting period in their life isn't all smooth sailing.
The star revealed that he and Argentinian-born Luisana can't agree on a name for their baby son, due to be born in August.
"My wife is killing me; we fight about the names," he tells People magazine. "She keeps coming up with names that she thinks sound good in Spanish, like 'Dirt.' Dirt Bublé!".
Michael also revealed he has been serenading his unborn child with his smooth vocals. "[I was singing to the baby] early on, really early on, and I didn't know because I've never had a baby before - and in the middle of singing my wife starts laughing and says, 'The baby is two months and has no ears to hear you!'".
Earlier this year, Luisana announced news of her pregnancy on Twitter. She posted a 20-second video that showed 'Mini Bublé's first ultrasound scan as well as a picture of the happy couple.
Playing in the background was Michael's track Haven't Met You Yet, which he co-wrote especially for his lady. The glamorous blonde also appeared in the song's music video.
An additional message on Luisana's Facebook page read, "Thank you to my friends for being as happy as I am and for giving me the most beautiful hugs and thank you God for giving me such a great happiness and the oppurtunity that a woman can have."
Canadian crooner Michael Bublé married his Argentine love in March 2011. The couple said 'I do' in a romantic religious ceremony at the historic Villa Maria, in Maximo Paz, located about an hour from Buenos Aires, the scene of their earlier civil marriage.
More than 300 guests, including the bride and groom's parents, watched as Michael and Luisana exchanged their emotional vows.
It's a little princess!
