He went from one child to four in five months and he apparently wants another three to hit the "magic number".
Cristiano Ronaldo is one of the world's best and highest-paid athletes in the world, plus he's officially the most followed user on Instagram with 172 million followers.
But while football fans can't get enough of Ronaldo's process on the field, his life outside of sport is equally intriguing.
For seven years, Ronaldo only had one son, Cristiano Ronaldo Jr.
Then — over just five months in 2017 — his brood blossomed to four.
While we know his current girlfriend Georgina Rodriguez gave birth to his youngest bub, the other two mothers of his children remain a mystery.
We explore Ronaldo's enigmatic family dynamic and why a young, straight millionaire like Ronaldo decided to use a surrogate.
Who is Cristiano Ronaldo Jr’s mum?
Ronaldo's oldest son is known as Cristianinho, or little Cristiano.
The eight-year-old was born in San Diego in 2010, while Ronaldo was dating model Irina Shayk.
"It is with great joy and emotion that I inform I have recently become a father to a baby boy. As agreed with the baby's mother, who prefers to have her identity kept confidential, my son will be under my exclusive guardianship," the sports star explained in a statement back in 2010, just after his team was kicked out of the World Cup.
"People speculate I was with this girl or another, or there was a surrogate mother," he told chat show host Jonathan Ross.
"I have never told anyone and never will," he said.
"When Cristiano [Junior] is going to grow up, I am always going to say the truth to him because he deserves it because he is my son, but I am not going to say because people want me to say."
Cristianinho has been an omnipresent fixture by his dad's side, often collecting awards alongside his famous dad and starring in his CR7 clothing line ads.
Did Ronaldo have his twins via surrogate?
In June 2017, he had twins via a surrogate — Eva and Mateo Ronaldo.
Just like their older brother, the one-year-old twins were born in San Diego.
The announcement shocked many, given that surrogacy comes with an exorbitant price tag (commercial surrogacy is actually illegal in Australia, but common around the world, particularly the US) and Ronaldo, still, a young man then, had a girlfriend at the time.
Manhattan fertility expert Dr. Joel Batzofin told The Post it's rare for single men, especially straight males, to choose surrogacy.
"Most people do surrogacy as a measure of last resort," Dr. Batzofin told the publication.
"I'm not going to tell you it's hugely common but I [do] see it now more than I did five years ago."
The process can cost up to $100,000, but given Ronaldo's reported pay packet of $93 million, that's hardly a splash in the pool.
"Cristiano Ronaldo will not share any reason as to why he chose a surrogate mother, he is simply grateful that he now has twins," a rep for the soccer star said last year.
Then just a month later, Ronaldo announced his girlfriend Georgina Rodriguez was pregnant with his fourth child.
The blended Ronaldo family
But despite the unusual family situation, it seems everyone gets along swimmingly, with Ronaldo's new girlfriend sharing a gorgeous happy snap of the blended family all hanging out together on a private plane.
Georgina captioned this photo below "Good day with love!" with all four of the kids present.
Good on them, we say!
