Australian singer/songwriter Missy Higgins has become a first-time mother after welcoming a son.

The Scar hitmaker gave birth to a little boy named Samuel Arrow Lee, her first child with fiance Dan Lee, on Monday (05Jan15).

She posted a picture of the new arrival on her page and added in a caption, "Our little boy Samuel Arrow Lee arrived yesterday. Not sure how we managed it but he seems perfect. And we're besotted! Let the adventures begin..."

Higgins is reportedly planning to take a year-long break from music to focus on motherhood.
