Cycling star Lance Armstrong is expecting a baby with his girlfriend, Anna Hansen, in June, the seven-time Tour de France champion has announced.
Armstrong said: "Anna and I are thrilled to confirm that we are expecting in June and our families are ecstatic and grateful."
The 37-year-old American has three children from his previous marriage with Kristin Richards.
After being diagnosed with testicular cancer in 1996, Armstrong underwent chemotherapy treatment as the cancer spread to other parts of his body.
The children with his ex-wife were conceived using sperm Armstrong stockpiled prior to his cancer treatment.
It was initially thought the chemotherapy would leave him unable to have further children.
This time the couple are expecting without the use of artificial fertilisation.
