Sharp, who is currently on loan to Forest from Southampton, and his partner Jade Fair are celebrating after the birth of a baby boy.
Both mother and baby are doing well and the couple have named their baby Leo Sharp.
It is happy news for the couple who were devastated after their first baby, Luey Jacob, died in hospital aged just two days last October.
In a statement released on behalf of the Luey Jacob Sharp Foundation today, Sharp said: "Jade and I are absolutely delighted with the safe arrival of our beautiful boy Leo.
"As everyone knows, we tragically lost our first son, Luey Jacob Sharp, so the birth of Leo makes this special time for our family especially poignant.
"We would like to thank our family and friends for the support they have given us throughout Jade's pregnancy.
"We are thrilled to become parents and we welcome Leo into our world with lots of love and are looking forward to starting family life together with our son."
The Luey Jacob Sharp Foundation helps families affected by gastroschisis, an abdominal-wall defect usually picked up by week 14 in pregnancy and the cause of which is still unknown.
Last year Sharp played for former club Doncaster just days after losing Luey on October 29. He called his goal in that match the most important of his career.
After scoring, Sharp lifted his shirt to reveal a message which read: "That's for you, son."
He tweeted later that night: "My goal tonight was the most important goal of my career dedicated to my brave boy luey jacob sharp I love u son sleep tight.thatsforyouson."
