Enrique Iglesias: Anna Would Be an 'Ideal' Mom
Enrique Iglesias is serious about girlfriend Anna Kournikova: In fact, he calls their romance "the only serious relationship I've had in my life."

But when asked if he sees himself with her down the road, the singer, 31, tells PEOPLE en Español in its new issue: "I don't know.

"The only thing I can say is that, in my opinion, Anna, whether we are together or not, would be an ideal mother. I think she'd be the perfect mother, and I say it regardless of whether I'd be with her or not."

In 2004, rumors circulated that the singer and the Russian tennis player, 25, had gotten married, but a source told PEOPLE at the time that it wasn't true.

Though Iglesias would not comment back then, he now tells PEOPLE en Español that he and Kournikova are living one day at a time, often spending all day together in Los Angeles or Miami, where each has a home.
