The twins, who are said to have been named Mateo and Eva, were born on Thursday 8 June, according to The Mirror.
Ronaldo is already dad to seven-year-old Cristiano Jr.
In March 2017 it was first reported that Ronaldo was expecting twins, however he did not confirm the news.
“He feels the time is right for his boy to have brothers to grow up with,” a source told The Sun at the time.
“His mum Dolores will be there to lend a helping hand like she has been with little Cristiano.”
We can’t wait to see a picture of the adorable tots.
