Lance Armstrong has super sperm!
Sources reveal exclusively to PerezHilton.com that the multiple Tour De France winner is expecting a child with his girlfriend, a non celeb.
"Lance and Anna [Hansen] have been quietly dating since July," a source tells us. "They met through Lance's charity work. Anna works at a non-profit for cancer survivors."
The two are said to be "thrilled" with the joyous baby news.
After Armstrong found out he had testicular cancer in the '90s, he had his sperm frozen. The three children Lance had with his ex-wife were conceived through in vitro.
Now, all these years later, his sperm is active again - something that only occurs in a handful of testicular cancer survivors.
Lance and Anna's baby was not planned but it's a little miracle.
"They couldn't be happier," a source tells us.
