Enrique Iglesias and Anna Kournikova Headed for Break-Up?

After 12 years together, it looks like Enrique Iglesias and Anna Kournikova could be headed for a split.

The Huffington Post reports that the Russian tennis star is ready to get married...but she's tired of waiting for Iglesias to get down on one knee and propose.

“Anna is getting tired of waiting for him to decide if he wants to marry her or not,” a source told New York Post's Page Six, “They’ve been together for so long, she feels like it’s never going to happen. She is ready to move on.”

However, the source said not all hope was lost for the Spanish singer, “This issue has come up before, and they have managed to smooth things over and get back together. Time will tell.”
