Anna Kournikova has sparked rumors she will wed singer Enrique Iglesias - after the tennis star was photographed with a huge diamond ring on her wedding finger.

The couple, together for seven years, cruised by boat along the coast of Miami, Florida earlier this month, when the blonde beauty, 27, was photographed wearing the sparkler. The pair has shared a home in the city for the last eight months.

A source tells Star Magazine, "Everyone is talking about Anna getting engaged. She is wearing a gorgeous ring on her left ring finger. Anna is being really coy about the rumors. She isn't denying anything, and she has a big smile on her face."
