The longtime couple are said to have welcomed twins, a boy and a girl, TMZ reports. The outlet says the babies’ names are Nicholas and Lucy, and that they were born on Saturday, Dec. 16, in Miami. Reps for the musician and the athlete did not immediately return PEOPLE’s request for comment.
The newborn babies are the first children for both Iglesias, 42, and Kournikova, 36, who have been together for over a decade and a half.
“I absolutely want to have children, whether I have my own or adopt,” said the Russian retired tennis star, adding, “I love taking care of people.”
Continued Kournikova, “[Marriage] isn’t important to me. I’m in a happy relationship– that’s all that matters … I believe in commitment. I believe in being open and trusting each other and respecting each other completely.”
And according to Iglesias, Kournikova is more than the right fit for the job of mom. Speaking to PEOPLE en Español in 2007, the singer admitted, “The only thing I can say is that, in my opinion, Anna, whether we are together or not, would be an ideal mother.”
“I think she’d be the perfect mother, and I say it regardless of whether I’d be with her or not,” added Iglesias of The Biggest Loser alum.
“#letsdothis 💪🏻😂🐾😉 ,” Kournikova captioned the clip, in which she’s wearing a loose-fitting tank top while working with resistance bands as two dogs look on from more relaxing lounging positions.
