The family of the hunky Portuguese soccer superstar tells the weekly Expresso that the baby, born June 17, is named Cristiano.
Ronaldo, 25, and his girlfriend, Russian model Irina Shayk, have been vacationing in New York as word has spread about the birth. The athlete announced the baby's arrival via Facebook and Twitter, neglecting to offer any word about the mother. His management company had no comment.
Expresso reports that little Cristiano weighed 9 lbs., 8 oz., and measured 21 in. at birth.
As the parents spend much of their holiday in such downtown Manhattan hotspots as SoHo House and the Gansevoort Hotel, the baby is in Portugal, being cared for by Ronaldo's mother Dolores, 55, and sister Kátia Aveira – who's been quoted as saying the infant "looks like his father and like me. He has the same eyes."
She also tells Correia da Manha,, "We're very happy. The baby is well, it's healthy and that's what matters."
