Seven-time Tour de France champion Lance Armstrong announced the birth of his son on Twitter Thursday night.

He wrote: “Wassup, world? My name is Max Armstrong and I just arrived. My Mommy is healthy and so am I!”

Lance was in Rome for the Giro d’Italia grand tour when he posted the message. He was kind enough to post a picture of the baby online, as well.

Girlfriend Anna Hansen delivered Lance’s fourth child—their first baby together.

Max, who weighed in at 7 lbs., 5 oz and is 20 inches long, joins siblings Luke, 9, and twins Isabelle and Grace, 7, from the cyclist’s previous marriage to Kristin Armstrong.

Lance and Anna announced the pregnancy in December.
