Levine, 35, said marriage has changed him for the better, reported People magazine.
"The relationship doesn't change but I have... in a great way. Marriage makes you slightly more masculine. If it's the right marriage, if it's the right person, the guy feels a little bit more like a man," he said.
Levine and wife, 25, started dating in 2012 but broke up the next year. They later reconciled and became engaged in July 2013. The couple got married on July 19, 2014 in Mexico. It is a first marriage for the couple.
