Father-to-be Michael Bublé has opened up about the process of naming his unborn son and revealed that his wife, model Luisana Lopilato, is coming up with some unusual ideas that he isn't too keen on.

During a recent interview on BBC America's The Graham Norton Show, the 'Haven't Met You Yet' hitmaker confessed that he often argues with his wife about potential names because she suggests odd things for their baby:

"My wife is killing me. We fight about the names. She keeps coming up with names that she thinks sound good in Spanish, like 'Dirt.' Dirt Bublé!"

Speaking about the baby's conception, Bublé said: "There was nothing sexy about it. My wife is so beautiful but it wasn't like that. She was very, 'You know what Mike? It's nine o'clock on Tuesday night and we must do it now.'"
