Cyclist Lance Armstrong and GF Anna Hansen Welcome Baby Boy [PHOTOS]

Anna Hansen and her Pro cyclist boyfriend, Lance Armstrong welcomed their newborn bay boy, Max Armstrong into the world Thursday night, and promptly announced the birth with a photo posted to Twitter.

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

Little Max weighed 7 pounds, 5 ounces and is 20 inches long.

What makes the birth of Max somewhat special is that Lance Armstrong is a survivor of testicular cancer. He has three children with his ex wife, Kristen, all conceived through invetro fertilization due to the cancer treatments, but Max was reportedly conceived naturally.
