Somebody has been scoring with super hot soccer star Cristiano Ronaldo and it's not his girlfriend, Russian model Irina Shayk. Gasp! This weekend he Tweeted some big news. "It is with great joy and emotion that I inform I have recently become father to a baby boy," he said. "As agreed with the baby's mother, who prefers to have her identity kept confidential, my son will be under my exclusive guardianship." So, uh, who is Ronaldo's baby mama? We may never know.

I'm already over that. Let's talk about how he's planning to be a single daddy. So sexy. After the jump, more celebrity single dads.
