Lance Armstrong is a daddy once again!

The seven-time Tour de France champ thought his baby-making days were done after he was diagnosed with testicular cancer a few years ago, but on Thursday Lance announced the arrival of his new baby boy in a Twitter message to fans. Baby Max weighs 7 pounds, 5 ounces and is 20 inches long. This is the biker dad’s first child with girlfriend Anna Hansen.

“Wassup, world? My name is Max Armstrong and I just arrived. My Mommy is healthy and so am I!” a proud Lance tweeted on his newborn son’s behalf.
