Enrique Iglesias and Anna Kournikova’s twins are getting so big!

Double the cuteness! Anna Kournikovashared a picture of her 6-month-old twins Nicholas and Lucy sporting Russian and Spanish soccer uniforms on Sunday, July 1, in honor of the 2018 FIFA World cup. The game — it ended in a draw — had special meaning for the former tennis pro and her longtime love Enrique Iglesias: She’s originally from Moscow and he’s from Madrid.

Earlier this month, the 37-year-old athlete posted an Instagram snap of a grinning Nicholas clutching a plush blue and red Russia soccer ball made for kids. Grammy-winning singer Iglesias, 43, meanwhile, Instagrammed a shot of Lucy resting on his shoulders as they watched a match together on June 15.

The couple kept the pregnancy completely under wraps and surprised fans by unveiling photos of the babies in January. Kournikova and the chart-topping artist are so private that even though they’ve been together for more than 16 years, neither has ever confirmed they are in a relationship. While Kournikova wears a yellow diamond on her ring finger and Iglesias referred to her as his “wife” during a 2017 concert, he insists they have never made it official.

“We’re just as happy. There comes a point when you’ve been with someone for a certain amount of time and I believe that you are like, married,” Iglesias told The Sun last year. “I guess the only difference is that we haven’t walked down the aisle.”

Kournikova and Iglesias first met on the set of the video for his 2001 hit “Escape.”
