Proof That Enrique Iglesias's Biggest Fan Is (and Always Has Been) Anna Kournikova

Enrique Iglesias and Anna Kournikova may have been together for 15 years. . . or they may not have. The couple, who are usually super private about their relationship, have managed the seemingly impossible feat of maintaining almost complete seclusion as well as global fame. We don't know much about Enrique and Anna's romance, but she just made one very sweet — and very public — gesture that proves the duo are rock solid.

Anna took to social media this month not only to show off her dance moves, but also to show how much she loves Enrique's new music. After posting a video of her and Enrique's dog listening to Enrique and Pitbull's "Messin Around", it was time for Anna to take center stage.

Anna posted a series of new videos showing herself during two dance sessions to Enrique's latest solo single, "Duele el Corazón". The first was filmed, apparently, somewhere in the couple's home, as Anna rocked out alongside their dog. "I am still enjoying my Saturday night dancing with my crazy dog," she wrote. Later, Anna showed off her dance moves while listening to the track on a boat. "Dancing marathon continues," she captioned the shot. In a follow-up video, she used the hashtag #dancingfool. Just days later, Anna shared a snap with Enrique — the first photo we've seen of the pair in a while.
