The romance between Russian tennis beauty Anna Kournikova and Enrique Iglesias is “on the rocks” after 12 years, sources exclusively tell Page Six.

We’re told the couple have hit a rough patch because the singer — son of legendary Spanish crooner and international ladies’ man Julio Iglesias — isn’t rushing into marriage despite more than a decade with the beautiful blond former pro court star.

A source tells us, “Anna is getting tired of waiting for him to decide if he wants to marry her or not. They’ve been together for so long, she feels like it’s never going to happen. She is ready to move on.”

But the source added, “This issue has come up before, and they have managed to smooth things over and get back together. Time will tell.”

Despite rumors in May that 38-year-old Iglesias and 32-year-old Kournikova were imminently due to tie the knot, his management team insisted that they have “no intention” to marry in the near future.

Last year, the singer was forced to deny they had secretly wed after calling Kournikova his wife, in Russian, while at a gig in her native country.

A spokeswoman for Kournikova didn’t get back to us by deadline, and reps for Iglesias declined to comment.
