Baby on board! Alanis Morissette is pregnant!

The singer is expecting her second child with husband Mario 'Souleye' Treadway.

People magazine confirmed that the 41-year-old is eating for two after Alanis announced the news on her website on Feb. 12 in an animated video and song.

The nearly 5-minute song, called "Souleye + Ever + Me + Love = Sweetness," was written years ago.

"The story of my nuclear family in moving pictures, brings us up to this sweet moment," she captioned the video. "[The song was] written, recorded and produced in 6 hours on May 22, 2010 with Guy Sigsworth, on the sly, to surprise Souleye. Brendan Huza helped tell our story. May this song take on ever-deepening meaning as each year goes by."

At the end of the video, an animated sonogram is shown, following by images of the family looking at a three-picture strip of sonogram photos.

Alanis and Mario were married in 2010. They have one one child together, 5-year-old son Ever Imre, hence the "Ever" in the song title.

It's not known how far along she is in her pregnancy.
