Amy Lee has given birth to a baby boy called Jack Lion.

The Evanescence singer and her therapist husband Josh Hartzler have welcomed their first child into the world and showed off the first picture of the little boy on the 'Bring Me To Life' hitmaker's Instagram page yesterday (28.07.14).

She captioned her cute photograph: ''Our little cub, Jack Lion Hartzler, is here. I have never known the depths of my heart till now. The world just exploded into technicolor,''

Jack is the first child for both Amy and her spouse after being married for seven years.

In January, the 32-year-old singer shared the happy news that she was expecting a baby with her followers on Twitter.

Amy wrote: ''Ok I can't keep it a secret anymore -- I've been working on a very special new project for 2014 - A BABY! (sic)''

She then added: ''Josh and I are expecting! I'm so happy!''

Since then, Amy has used her social media pages to share photos from the baby's new nursery, which features a hand-painted mural of a mother giraffe kissing her baby.
