What In the world is going on with Anna Kournikova?

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.

The pair teamed up for Iglesias’ 2001 music video “Escape,” which would help seal the deal on their love. The video, which features Kournikova playing coy against advances from Iglesias before ending in a makeout session, was the first time fans caught a glimpse of their chemistry.

Iglesias and Kournikova welcomed twins Nicholas and Lucy on Dec. 16, 2017, in Miami after keeping the pregnancy a secret. Though reps for Iglesias and Kournikova did not initially confirm the news to PEOPLE, the new parents posted shots of the twins on both of their Instagram accounts shortly after the birth.

A month after giving birth, Kournikova posted a video of herself dancing to Iglesias’ song “E Baño” on the pair’s boat, and fans couldn’t help but notice how fit she looked after welcoming twins. That same month, the Russian tennis pro gave her followers a sneak peek into her workout regime on Instagram.

Though both Iglesias and Kournikova had shared photos of their babies, neither had said much about the experience until Iglesias took the stage in Budapest, Hungary, and discussed his newfound fatherhood with fans.

“I became a father 12 weeks ago and I can absolutely tell you two things: I love my babies! I love them very much,” he told the crowd at the Budapest Sports Arena. He also praised Kournikova saying, “I love my girl” before dedicating a song to both her and his loyal fans.

In an interview with The Sun, Iglesias opened up about how the birth of their twins affected their relationship in the bedroom. “It’s probably more sex now than ever. The sex has not diminished,” he said at the time.

He also discussed watching Kournikova become a mother for the first time, saying, “It’s incredible to watch her be such a great mother. It’s incredible to watch a mum do what she does, when a mother’s instinct kicks in.”

Their family expanded once again in 2020 with the arrival of their daughter Mary, affectionately nicknamed Masha. Her birth was announced by Iglesias, who captioned a sweet photo of himself holding the newborn at the hospital: “My Sunshine 01.30.2020.” Kournikova followed suit and posted a photo of herself holding Mary just after giving birth via C-section.

Iglesias has marveled at the twins’ smooth transition into older siblings; “They actually love it,” he said, of the twins. “There’s a two-year difference, so I was a little scared. I was like, ‘How are they going to react?’ And I have two dogs so my house is chaotic.

When we first came home with Masha, I was like, ‘Oh, how is everybody going to react?’ ” highlighting the love and chaos that define their bustling household.

As the world continues to speculate about their private lives, one thing is clear: the enduring love story of Enrique Iglesias and Anna Kournikova continues to captivate and inspire fans worldwide.
