Anna Kournikova and Enrique Iglesias have been in a on-again, off-again relationship for over 15 years. But despite the long-term relationship, the couple haas shared little to no pictures of one another. However, that now seems to be changing. The former tennis star posted a new photo of herself this week with the Spanish singer and her little brother Allan Kournikova. And if that wasn't enough, Kournikova also recently shared a video of herself dancing to Enrique's newest hit, "Duele el Corazon," Kournikova and Inglesias first met on the set of the singer's "Escape" music video back in 2001.
