Anna Kournikova and Enrique Iglesias might be breaking up after 12 years together.

According to Page Six, the couple have hit a rough patch because the singer isn’t rushing into marriage despite more than a decade with the Russian tennis star.

"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," a source told the paper.

"This issue has come up before, and they have managed to smooth things over and get back together. Time will tell."

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

He said: “It was just meant to be sweet... I honestly didn’t mean to confuse people. I thought it'd be easier for the audience to understand than if I said she was my girl.”

In 2012, the singer addressed engagement and wedding rumors. 

"I've never really thought marriage would make a difference. Maybe it's because I come from divorced parents, but I don't think you love someone more because of a piece of paper," Iglesias told Parade.

Luckily for Iglesias, Kournikova shares his view on marriage. "It isn't important to me," she told Women's Health in 2011. "I'm in a happy relationship -- that's all that matters."
