Lance Armstrong is a father -- again!
The 39-year-old cyclist announced the birth of his second child with girlfriend Anna Hansen early Monday morning via Twitter (they welcomed son Max in 2009).
"Olivia Marie Armstrong has arrived!" Armstrong tweeted.
"I'm 'bout ready to get outta here!" the newborn "tweeted" Monday.
The Tour de France champion has three other children with ex-wife Kristin Richard: Luke, 11, and twins Isabelle and Grace, 8.
