Still, she's keen to get back to work and has revealed she is already inspired to write a new album.

"This whole incredible thing that's taken part in my life, between the pregnancy and the birth, I've got so much to be inspired about and so much in my life to write about.

"I've been brainstorming for the last nine months of my pregnancy. This next album will have a whole new me. A different me."
