"Wassup, world? My name is Max Armstrong and I just arrived. My mommy is healthy and so am I!," Armstrong wrote on his Twitter page.

Congrats and all to Armstrong and his family, but wasn't the reason the Tour de France champ and Sheryl Crow broke up was because he didn't want any more kids?

Wonder what changed his mind?
