Anna Kournikova: I May Never Marry Enrique Iglesias

They've been together for a decade, but tennis pro Anna Kournikova says she has no immediate plans to wed Latin singer Enrique Iglesias, 36.

"[Marriage] isn't important to me. I'm in a happy relationship -- that's all that matters," the 30-year-old tells the November issue of Women's Health.

"I believe in commitment," she adds. "I believe in being open and trusting each other and respecting each other completely."

Even if she never makes it down the aisle, Kournikova won't give up her dream of becoming a mother.

"I absolutely want to have children, whether I have my own or adopt," the Biggest Loser trainer tells Women's Health. "I love taking care of people."
