Baby No. 2! Alanis Morissette reveals she's got a bun in the oven

Baby makes four!

Alanis Morissette announced she's expecting her second child with her husband, rapper Mario "Souleye" Treadway, in an adorable video posted to her website on Friday.

The "Ironic" singer titled the video, "SOULEYE + EVER + ME + <3 = SWEETNESS," and it showcased moving pictures of Morissette, Treadway and their 5-year-old son, Ever, over a sentimental song that Morissette recorded with Guy Sigsworth. At the end of the very sweet video, the three are seen looking at an ultrasound of their new little bundle of joy.

The video's description says it was written and recorded to "surprise Souleye."

Naturally, the 41-year-old singer's hubby thought the video was too sweet and he shared his own sweet words about the video.

Congrats to the happy family!
