The My Kitchen Rules judge announced the happy news on Facebook this afternoon.
"I'm excited to be able to share this brilliant news with you all, my fiancée Clarissa and I are expecting a little girl in the new year!" Feidel wrote.
"We are both over the moon and can't wait to meet our daughter!"
It will be the first daughter for Feidel, who has a son from a previous relationship.
The French chef and the jewellery designer became engaged in November last year.
