(Cover) - EN Showbiz - Alanis Morissette wrote her new album between "being under the rock and wearing sweatpants".

The Canadian musician released her EP Havoc and Bright Lights Tuesday after a four-year musical hiatus.

Alanis was pregnant with her son Ever Imre in 2010 and was not in the mood to compose new songs.

"I was dying to write this record. I find there are ebbs and flows to the whole cycle of being under the rock and wearing sweatpants, and then coming out and putting 16-inch heels and glitter on and sharing the conversation-starting songs," she told MTV News.

"I wanted to write when I was pregnant, to be honest, but I was down for the count, on the couch, at 3 p.m. every day, so that wasn't going to happen. So I built a studio in my living room, and Guy Sigsworth, the producer, came over from London, and we wrote together. And my son was five-and-a-half months old, and I just breastfed, and he trumped everything, his needs were number one, and we wrote between those times." (C) Cover Media
