This morning, Justine Henin announced the birth of her new baby boy on her official Facebook page.
She wrote: "Yesterday morning, a little prince came into our lives.
"His name is Victor and already fills us with joy."
Henin, a seven-time Slam champion and former WTA World No.1, was one of the defining players of women's tennis at the turn of the millennium.
Victor is her second child with husband Benoît Bertuzzo following the birth of their daughter, Lalie, in 2013.
