Liv Tyler has welcomed her first daughter, Lula Rose Gardner.

The 39-year-old actress posted the news on Instagram on Sunday alongside a picture of the newborn. She writes, “We are sooooo happy,” adding, “heart exploding with love.”

It’s the third child for Tyler and her second with partner David Gardner. Tyler has two sons: 11-year-old Milo and 17-month-old Sailor.

The birth also means a new grandchild for Tyler’s famous father, Aerosmith frontman Steven Tyler.

Liv Tyler is set to star in the final season of “The Leftovers” next year on HBO.

The actress spent much of her youth in Portland and attended Waynflete School. She is the daughter of singer Bebe Buell and a granddaughter of Dorothea Johnson of Falmouth, an etiquette expert.
