Ira Losco gave birth to a baby boy last night, the singer's partner Sean Gravina announced on Facebook early this morning.
"Our baby Harry was born last night and Ira is recovering perfectly, she was great," Mr Gravina wrote, adding that the delivery "wasn't an easy one."
Mr Gravina thanked Mater Dei hospital staff for their care and attention.
Ms Losco had announced that she was pregnant back in May, in the run-up to this year's Eurovision Song Contest.
At the time, she had told fans "I'm ecstatic that my boyfriend Sean, family and friends are here to support me all the way. To add to all the excitement I'm also celebrating my First Mother's Day as a mother-to-be."
Ira Losco is one of the biggest names in Maltese music, and her career spanning over 15 years has seen her win more than 20 music awards. She has represented Malta twice at the Eurovision Song Contest, placing second in 2002 and joint 11th/12th place at the festival in Stockholm last May.
Beyond music, she is an advocate for LGBTI rights, supports anti-bullying initiatives and campaigns to help teenagers protect themselves from revenge porn. In 2008 she was awarded a medal by the President of Malta in recognition of her achievements.
