"I've never really thought marriage would make a difference. Maybe it's because I come from divorced parents, but I don't think you love someone more because of a piece of paper," Iglesias tells Parade.
That doesn't mean the "I Like It" singer isn't committed to the tennis pro, 30. "Nowadays, it's not taboo to have kids and not be married," he explains. "What makes a difference is that you're a good parent, period."
Iglesias, 36, confused fans when he referred to Kournikova as his wife during a concert in Russia in April 2011. "It was just meant to be sweet in the moment," he tells Parade. "I thought it'd be easier for the audience to understand than if I said 'my girl.'"
Luckily for Iglesias, Kournikova shares his view on marriage. "It isn't important to me," she told Women's Health in 2011. "I'm in a happy relationship -- that's all that matters."
