Cycling ace Lance Armstrong has received good news in time for Christmas - the sports star is reportedly set to be a dad for the fourth time. The testicular cancer survivor is said to be "thrilled" after naturally conceiving a child with girlfriend Anna Hansen.

A source tells gossip blogger Perez Hilton, "Lance and Anna have been quietly dating since July. They met through Lance's charity work.

Anna works at a non-profit (charity) for cancer survivors... They couldn't be happier."

The seven-time Tour De France champion had his sperm frozen after he was diagnosed with cancer in 1996. His three other children with ex-wife Kristin Richards were conceived through in vitro fertilization.
