"Alanis Morissette and Mario 'Souleye' Treadway welcomed a baby boy, Ever Imre Morissette-Treadway, on Dec. 25th," says a rep for the new mom. "All are healthy and happy."
The prolific singer/songwriter, 36, announced her pregnancy in August. She and Treadway, 30, married on May 22 at their Los Angeles home.
Morissette admitted before the birth that the pregnancy had been a surprise, albeit a happy one.
She enjoyed one last send-off before motherhood commenced, and was seen beaming and showing off her bump at a baby shower in October.
