Proud new mom-of-two Liv Tyler announced her son’s name Friday via Instagram.

The Leftovers actress, 37, and her boyfriend, sports manager/agent David Gardner, welcomed their baby boy on Feb. 11. “He’s healthy and everyone is very happy,” her rep said at the time, remaining mum on the moniker.

But on Friday afternoon, the newborn’s nautical name was revealed with a photo of her sweet tot holding a blue stone necklace featuring a diamond encrusted anchor.

The Armageddon star captioned the image: “Sailor Gene Gardner.”

Sailor is the actress’ second son — she welcomed Milo in Dec. 2004 with ex-husband Royston Langdon.

Gardner is also dad to 7-year-old son Gray from his previous marriage.
