Marriage isn't important to Anna Kournikova.

While the 30-year-old Russian beauty has been dating Enrique Iglesias for nearly 10 years, she says the pair are not in any rush to get married although she hasn't ruled out having children in the near future.

She told Women's Health magazine: "[Marriage] isn't important to me. I'm in a happy relationship - that's all that matters. I believe in commitment. I believe in being open and trusting each other and respecting each other completely.

"I absolutely want to have children, whether I have my own or adopt. I love taking care of people."

Earlier this year, Anna put her seven-bedroom Miami mansion on the market for $9.4 million, sparking speculation she and Enrique were thinking about marriage.

The luxury house was built in 2000 and contains a covered entertainment area, outdoor swimming pool, a boat dock and outdoor kitchen and barbecue.

Other features of the mansion include a coral rock pool deck surrounding the pool and a two-storey guest house with a kitchen and separate living space.
