Missy Higgins has given birth to her first child, a boy.

The Aussie singer Instagrammed a picture of her new son, with playwright fiance Dan Lee, this week.

"Our little boy Samuel Arrow Lee arrived yesterday (Monday). Not sure how we managed it but he seems perfect. And we're besotted," the new mum captioned the snap, right.

"Let the adventures begin . . ."

Higgins and Lee, who hails from Broome, became engaged last January after a whirlwind eight-month romance.
