Grammy-winning artist Alanis Morissette, 36, has something to sing about -- a new bundle of joy!

Alanis and hubby, rapper Mario "Souleye" Treadway, 30, welcomed a baby boy, Ever Imre Morissette-Treadway, on December 25th.

A spokesperson for Alanis says, "All are healthy and happy."

The musical pair wed on May 22, 2010, a first marriage for both. Souleye, the Massachusetts-born rapper who has worked with bands such as Sound Tribe Sector 9 and the String Cheese Incident, began dating the Canadian crooner in 2009.

The "Ironic" singer announced her pregnancy in August.
