Lance Armstrong has some new Twitter competition: his baby daughter.
The 39-year-old cyclist announced the birth of Olivia Marie Armstrong, but didn't give any specifics.
That said, Olivia already has a Twitter handle.
Olivia's first post-birth tweet? "Well, I made it out! What's happening? Sleeping."
Armstrong and girlfriend Anna Hansen have a 16-month-old son, Maxwell. Armstrong has 9-year-old twin daughters, Isabelle and Grace, and an 11-year-old son, Luke, with ex-wife Kristin.
