Enrique Iglesias and Anna Kournikova's Relationship Timeline

While celebrity appearances in music videos are not uncommon, they don't typically result in a long-lasting romance like that of Latin pop star Enrique Iglesias and former professional tennis player Anna Kournikova.

The pair met in 2001 on the set of the singer's "Escape" music video, where they engaged in a few steamy makeout scenes. Their chemistry translated well off-screen and they became an official couple shortly after. They have since welcomed three children together, but have never married.

Iglesias and Kournikova have kept their two-decade-long relationship out of the spotlight for the most part, but on occasion, they will share rare glimpses into their family life on social media.
