The 37-year-old actress gave birth to the baby, who she shares with entertainment manager David Gardner, on February 11.
And on Friday Liv shared the child’s name with fans on Instagram.
“Sailor Gene Gardner @davidgardner76,” she captioned an image of her baby’s hand holding a necklace with an anchor emblem.
Little Sailor came into the world six weeks before his due date. She is also mother to ten-year-old son Milo from her marriage to Royston Langdon.
Liv was surrounded by family in hospital, as her Aerosmith rocker father Steven Tyler was by the star’s bedside along with her half-sister Mia Tyler.
Steven said he cried over Sailor’s arrival.
“When I got the call that Liv Tyler was going into labor, after crying like a baby myself, I immediately dropped everything and went to the airport to get on the next available flight…(sic),” he wrote on Facebook. “When I landed I kept calling my daughter Mia Tyler who was already helping Liv and she kept giving me minute by minute updates, ‘HURRY THE BABY IS COMING!’”
Liv’s sibling Mia is also elated over the new addition to their family.
“There is nothing more special than helping to bring a life into this world with the most important people in your life,” Mia wrote on her own Facebook page. “So proud to be a part of it. And so very excited to have a new pup in our wolf pack. So much love in this pic.”
