Inset: Getty Images Enrique Iglesias Has Adorable Daddy-Daughter Dance with His 2-Month-Old Baby Mary Kournikova and longtime partner Enrique Iglesias welcomed Mary, their third child together, on Jan. 30. They also share 2½-year-old twins Nicholas and Lucy. "My Sunshine," the new dad of three, 45, previously captioned a photo of himself in the hospital holding his then-newborn daughter, who was sporting a beanie topped with a bow. The "Heart Attack" singer spoke with PEOPLE in March about welcoming Mary to the family, revealing her name and sweet Russian nickname: Masha. (Kournikova is from Russia.) Iglesias also said the transition for the couple's twins to the role of older siblings has gone "very smoothly," sharing that Nicholas and Lucy "actually love" having a baby around the house. "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?' " Nicholas and Lucy were the first children for both the singer and former pro tennis player, who have been together for almost two decades.
