Liv Tyler is going to be a mommy again! The "Leftovers" actress took to her official Instagram page on Friday to announce that she's expecting her third child. This marks the second child for Tyler and her fiancé, sports agent David Gardner, and he also took to social media to announce the exciting news.

The daughter of Aerosmith rocker Steven Tyler uploaded a photo of herself absolutely glowing with happiness, standing on a beach wearing a short black dress. Her hair was styled in loose beach-y waves and she smiled wide as she placed her hand over her baby bump, which is just barely noticeable.

"Oh my goodness it seems the stork is visiting us again !!!! I am growing another little Tyler Gardner in my belly . our family is growing!!! So grateful. @davidgardner I love you," the 38-year-old "Lord of the Rings" actress wrote in the caption.

Her fiancé uploaded another photo of Tyler wearing a white long-sleeved short dress. She stood on the beach with the ocean in the background, and she posed with her body turned to the side so that the camera could fully capture her growing baby bump.

"My beautiful baby is pregnant !!!! Sooooooo excited and so blessed, I love you @misslivalittle X," the proud dad-to-be wrote on Instagram.

The news comes less than one year after the couple welcomed their first child together, a son named Sailor, who was born last February, according to E! News. Tyler has a 10-year-old son named Milo from a previous marriage, and Gardner shares an 8-year-old son named Gray from a previous marriage. The couple has been engaged since last winter.
