Lance Armstrong’s latest set of wheels are attached to a stroller.
The seven-time Tour de France champion has welcomed a son with girlfriend Anna Hansen, their first child together and his fourth.
“Wassup, world? My name is Max Armstrong and I just arrived. My Mommy is healthy and so am I!” tweeted his star cyclist daddy Thursday evening.
Armstrong was kind enough to post a picture of the newborn online, as well. (He is totally rockin’ the hat look.)
Armstrong also has three children with ex-wife Kristin.
“Anna and I are thrilled to confirm that we are expecting in June and our families are ecstatic and grateful,” the cancer-survivng 37-year-old said in a statement in December, when he confirmed they were expecting.
