Her fellow nuns at the convent were quoted saying they were "very surprised'," The Examiner reported.
Local pastor Don Fabrizio Borrello told reporters that the nun plans to keep the baby, GlobalVille News reported.
Nuns are religious members of the Church who devote their lives solely to God and do not engage in sexual activity. This nun birth is a shock to just about everyone.
"I guess she's telling the truth when she says she arrived at the hospital unaware of the pregnancy," Borello added.

The mayor of Rieti Simone Petrangeli has asked the public and the media to respect the nun's privacy.
