The newborn twins are the first children for 42-year-old musician and the 36-year-old retired tennis star, who began dating in 2001. Kournikova even appeared as the love interest in the music video for Iglesias's 2001 song, "Escape."

The typically private couple kept the pregnancy under wraps. Reports that the two have been engaged and married haven't been verified by the couple beyond a very big rock on Kournikova's left ring finger and what appears to be a wedding band in rare photos of the athlete.

People reported that the couple is very rarely photographed together. Even on their respective Instagram pages, neither make an appearance, but a German shepherd named Max and a Chesapeake Bay retriever named Jack have been seen in multiple posts on each page.

Representatives for Kournikova and Iglesias did not respond to People’s requests for comment.
