Seven-time Tour de France cycling winner Lance Armstrong became a dad for the fourth time on Thursday with the arrival of baby Max Armstrong.

Lance and his girlfriend Anna Hansen announced the pregnancy back in December.

Max came into the world weighing 7 lbs. 5 oz. and at 20 inches long.

Armstrong announced the birth of Max on his Twitter page @lancearmstrong:

Wassup, world? My name is Max Armstrong and I just arrived. My Mommy is healthy and so am I!

During the pregnancy, Lance and Anna had called the unborn child the ‘Miracle Baby.’

Lance has three children from his first marriage to Kristin Armstrong, a son Luke and twin girls Isabelle and Grace.
