Liv Tyler is pregnant.

The Leftovers actress and her fiance Dave Gardner - who already have 11-month-old Sailor Gene Gardner - are expecting their second child together later this year.

Liv wrote on Instagram: "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 (sic)."

She added a picture of herself sporting a tiny baby bump.

Liv also has 10-year-old son Milo from her marriage to musician Royston Langdon while Dave has son Grey, seven, with ex-wife Davinia Taylor.

The couple currently divide their time between her home in New York City, his base in London and Austin, Texas, where she films her HBO series, but hope to be more settled in the future.

The brunette beauty previously said: "We're doing everything we can to be together, but right now because of work we're going back and forth."

And speaking about getting married again, she said: "I had this philosophy that you should only get married once. But then, of course, that changes. I definitely believe we have lessons we learn through our relationships. You're meant to work through and mirror each other. It's the thing in someone that drives you the most crazy that is maybe a part of yourself somewhere."
