Cristiano Ronaldo A Father: Who are the Sexiest Potential Mothers?

Big news from the world's most promiscuous playboy. Cristiano Ronaldo has given the world an heir to his title.

Ronaldo made a full social media blitz Sunday on Twitter, Facebook and his web page to announce that he has become a father.

"It is with great joy and emotion that I inform I have recently become father to a baby boy," the Portugal captain wrote. "As agreed with the baby’s mother, who prefers to have her identity kept confidential, my son will be under my exclusive guardianship.”

No date for the birth was given. The Real Madrid star made it clear that's about as much he's going to say.

“I request everyone to fully respect my right to privacy (and that of the child) at least on issues as personal as these are,” he said.

So while the rest of the world tries to figure out who the baby mama is, we're taking a different approach.

Ronaldo has been linked to more than 40 women over the last four years.

Being hot is a great start for this kid, but what about following dad to the pitch?

That's why we've ranked his conquests by how athletic their offspring would be.

20. Karina Bacchi

Karina is a big-time Italian soap opera star.

As far as athletic potential, the top heaviness may be a problem.

19. Diana Chaves

She's a European soap star as well who has been trying to break into American film for a while.

It's not that she's ugly. But we wouldn't want the kid to have a mom who has failed to reach her dreams. Too much bitterness.

18. Raffaella Fico

The Spanish model sold her virginity for $1.5 million.

Do you think Ronaldo joked to his friends that he just got his Fico score?

Oh, that's bad. I'm sorry.

17. Marina Rodrigues

Miss Portugal 2004 would make the parents happy that he found a native girl.

But she's reportedly more of a fan of dating athletes than actually competing in sport.

So while hot, that admission puts her lower on the list.

16. Imogen Thomas

The Miss Wales winner was a contestant on Big Brother UK and has moved on to basically be famous for taking sexy photos.

Oh, and she has a sex tape on the Web. That's the kind of thing that might be an embarrassment and roadblock to the baby's success.

15. Bipasha Basu

This Bollywood actress is absolutely stunning, but has chunkier curves than most of the women on the list.

Yeah, that's about all there is to differentiate these hotties.

14. Daniele Aguiar

The Braziian supermodel was one of Ronaldo's earlier WAGs.

That doesn't make her any less hot.

13. Niki Ghazian

Would you trust a lingerie football player to be your lawyer?

Niki's apparently hoping so. That's her career path right now. Though I don't see a whole lot of photos of her studying for law school tests on her Twitter page.

She seems more interested in partying, being dirty and landing Fernando Torres as her next WAG conquest.

12. Nereida Gallardo

She was broken up with via text message by Ronaldo.

The nursing student used the notoriety from the hookup to ditch the medical career and make modeling and being Ronaldo's ex her full-time gig.

11. Isabel Figueira

The model first became a WAG thanks to Ronaldo.

She apparently liked the lifestyle so much that she wanted in more permanently. Isabel married midfielder Cesar Peixoto a couple years later.

That's the best part of a man whore like Ronaldo. No long-term commitment issues to cloud the issue, but he lets you sample the WAG world for future reference.

10. Merche Romero

She's one of Ronaldo's earlier conquests. The two dated in 2006.

Romero is nine years older than Ronaldo but still just as hot as the rest of the top 20.

She looks like she's about to go for a run in this shot. Good enough proof for us.

9. Paris Hilton

Not for nothing, but the baby mama is reportedly American.

Who are we kidding? Paris couldn't be out of the tabloids for nine months.

She likes to hang out at the beach, which is often adjacent to volleyball games.

That's as much of a connection as we could make.

8. Letizia Filippi

Fillippi is an Italian model who was plenty happy to talk about her time with Ronaldo.

She once said that if he won the FIFA Player of the Year award, she'd take him on a plane and find a far-flung place to have for two or three hours.

With that kind of support of athletic endeavors, we like her to be a supportive sports mom.

7. Luciana Abreu

Luciana is a singer, an actress and a model. And she apparently likes bikini tops that double as fans or curtains.

We're big proponents of women posing near mirrors. That puts her in my top 10.

6. Gabriela Endringer

She's probably been the chattiest of the myriad of women in Ronaldo's black book.

She said Ronaldo was dominant in bed and very affectionate and that the two of them rarely left the bed at his house for a week.

She certainly has the body of an athlete and she likes to take photos around gym equipment. That's good enough for our top five.

5. Gemma Atkinson

If Ronaldo could not commit to this stunner, he's never going to settle down.

Even worse, he cheated on Gemma with a pair of hookers. That's just ridiculous.

She's a No. 1 by a landslide among the WAGs in hotness. But she's lacking the athlete cred for this list.

4. Kim Kardashian

We like Kim for so many reasons, including this eye-straining shot.

But the fact that she was able to forge a high-profile celebrity career out of nothing tells us that the pair's child would be ultra ambitious.

3. Luana Belletti

We may be on to something here.

Besides being ridiculous hot, Belletti is the sister of Chelsea star Juliano Belletti.

There's athletic genes there on both sides.

2. Irina Shayk

Shayk has reportedly been dating Ronaldo for six months. If she stays around after this news, she's going to have to be the stepmom.

The fact that this supermodel has appeared in Sports Illustrated is good enough proof for us that she has quality athlete genes.

1. Maria Sharapova

Let me be clear. This is not about who's hottest. On that scale, Sharapova is back in the middle of this pack.

We're talking about who would make pretty and athletic babies.

Sharapova is a gimme on this list.
