“I’m nervous and excited, and truly I think it’s given me great perspective,” the singer said at the music video shoot for his new single, “It’s a Beautiful Day.”

“I used to worry about how the single would do and how the record would sell. And the truth is, I love this record. I’m so proud of it. But, at the end of the day, if it sells 10 million or 10 copies, I’ve got bigger fish to fry,” he continued. “I’ve got a wife and a kid I love very much.”

Buble married Argentine actress Luisana Lopilato in 2011. They announced in January they’re expecting their first child, and his publicist confirmed Thursday the couple are expecting a son.

His new album, To Be Loved, will be released April 23. It finds the Grammy winner covering songs by the Bee Gees, Dean Martin and Elvis Presley, as well as collaborating with Reese Witherspoon. It also features four original songs, including a tribute to his wife called “Close Your Eyes.”

“It’s a Beautiful Day” is about a man who is happy because his failing romantic relationship has finally ended. So who inspired the song?

“Harry Styles,” the 37-year-old Buble replied jokingly, referring to the One Direction band member who dated Taylor Swift.

“Harry Styles,” Buble said again, feigning heartbreak. “He left me for Taylor. I’ll be writing about her, too, soon.”
