Liv Tyler has revealed a sneak peek of her new son Sailor – by posting a picture of his tiny feet online.

The 37-year-old actress welcomed her second child, her first with sports manager boyfriend David Gardner, last month. When he was born, a source told People he was six weeks premature and would need to remain in the hospital for a while, but he is now home with his mum.

Liv posted a picture of her manicured nails next to his tiny feet on Instagram and wrote “I’m so in love!!!”

The Leftovers star revealed her son’s name to be Sailor Gene Gardner when she posted a picture of his hand online two weeks ago.

Liv, the daughter of Aerosmith star Steven Tyler, is already mum to nine-year-old son Milo from her former marriage with Royston Langdon. And Dave has a seven-year-old son Gray from a previous relationship.

She confirmed pregnancy rumours on Instagram in October when she wore a “bun in the oven” costume for Halloween.
