Liv-in' and smiling! Liv Tyler shared several new photos of her adorable 6-month-old son, Sailor Gardner, on Monday, Aug. 17, finally revealing the little one's sweet face.

"Our beautiful baby boy," the Leftovers star, 37, wrote, alongside a snap of her baby boy, whom she shares with her boyfriend, Dave Gardner. In the pic, baby Sailor is dressed in a linen onesie and stares up at the camera with an amused expression. "Sailor Gene Gardner... 6 months old... so so sooooo in love and grateful @davidgardner."

Proud mom Tyler followed up with another black and white photo of her little one kicking one leg up and clutching his little toes with his tiny fingers.

While this isn't the first time Tyler has shared photos of Sailor, it is the first instance she's revealed his face. Gardner has also posted pics of their son without showing off his face.

The couple welcomed their first child together on Feb. 11, six weeks ahead of his projected due date. Tyler also shares a 10-year-old son, Milo, with ex-husband, musician Royston Langdon of Spacehog.

Sailor appears healthy and happy despite arriving early — and is surrounded by loads of love. Just last week, Tyler posted a pic of her Leftovers costar, newlywed Justin Theroux, meeting her son on the set of the HBO series.

"My #theleftovers family meeting my baby boy," the actress wrote, alongside a candid photo of Theroux kissing Sailor's hand. "@the_left0vers @hbo #justintheroux #margaretqualley . I feel so blessed in all parts of my life."
