The baby is Samantha's first with her American husband Torray Scales, who has a young son from a previous relationship.

Samantha married the policeman in 2012, and baby Sage has arrived just a week after they celebrated their third wedding anniversary.

The Dubliner, who now lives in LA also revealed in a blog post that she has already set up an email address for her new arrival, but don’t worry it’s for a good reason.

The singer has vowed to send Sage an email every year on her birthday, and when she is older she will give her the address and password so she can read them.

"Every year on her birthday I am going to write her an email and attach pictures of her/special moments from throughout that year.

"Close family members might send her ones too. When she is older I will give her the email address and password.

"I think it will be nice for her to have."
