Harding, 40, gave birth to a boy on Saturday in a Washington State hospital, The Oregonian reports.
"Everybody's healthy and happy," her friend Don Horn tells the newspaper.
"She's always wanted a baby," Horn adds. "She was told she could never have a child ... and guess what? It really is a miracle and she really is very happy."
It's the first child for Harding, who is married to Joseph Price, 42, and lives in Washington.
Harding gained prominence when she won the U.S. Figure Skating Championships in 1991, but became notorious after her ex-husband and bodyguard hired another man to injure her competitor Nancy Kerrigan's leg.
Harding pleaded guilty to hindering prosecution and was banned from amateur skating.
