After nearly five years of marriage, Michael Bublé and Luisana Lopilato are still in wedded bliss!

"My wife and I are two of the most supportive people that we know in a relationship," the 40-year-old singer said of his wife, 28, in a new interview. "She's my best friend. When something good happens, she's the first person I want to tell, and equally when something bad happens."

Michael and Lusiana first began dating in 2008 and tied the knot in March 2011. The happy couple are parents to a two-year-old son, Noah, and announced they are expecting their second child — another baby boy! — last July.

"My happiness is to be embedded with these two and they're my whole world, so the truth is I wouldn't be happy without them," the "Everything" singer said of his family. "I find no fulfillment being that Hollywood story that you hear about; that artist who leaves his family on a search for the perfect career. That won't happen here."

"There will have to be a healthy balance and if there's not, then only one thing is going to have to have to suffer, and let me tell you it won't be my family life," Michael added to People.
