Alanis Morissette pregnant

Alanis Morissette is pregnant with her second child.

The 41-year-old singer and her husband Mario 'Souleye' Treadway - who already have five-year-old son Ever together - will welcome another baby later this year.

Alanis posted a song with an animated video, which ends with the trio looking at an ultrasound picture, on her website and wrote: "The story of my nuclear family in moving pictures, brings us up to this sweet moment. [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."

Alanis - who married Mario, 35, in 2010 - previously revealed she is an advocate of attachment parenting.

Speaking when Ever was 16 months old, she said: "I breastfeed and I'll be breastfeeding until my son is finished and he weans.

"I think it affords the child, when he grows up, to have a lot less therapy to go to.

"For me, I protect his safety and his well-being and his attachment. That stage of development is a very important stage."
