Actress Liv Tyler is a mom again.

The actress and her fiance, sports agent David Gardner, welcomed their second child together over the weekend (09-10Jul16).

She posted a photo of Gardner cradling little Lula Rose in his arms on Instagram on Sunday (10Jul16) and added the caption: "Hello!!!!! Our beautiful baby girl is here!!!! Lula Rose Gardner We are soooooo happy. heart exploding with love!!!!!"

Liv and David are also also proud parents to one-year-old son Sailor Gene, while the 38-year-old star has an 11-year-old son, Milo, from her marriage to British rocker Royston Langdon.

Gardner also has an eight-year-old son from his marriage to actress and socialite Davinia Taylor.

Tyler announced she was pregnant in January (16), tweeting: "Oh my goodness it seems the stork is visiting us again... Our family is growing!!! So grateful. @davidgardner I love you."

The actress has also been posting her pregnancy progress on Instagram, and just last week (ends08Jul16), she captioned one shot: "Ohhhh my goodness look at that bump so pointy and giant!! I can't wait to meet the beautiful little human living in there..."

It appears the newborn will be Tyler's last baby - she recently said, "I have been pregnant for two years straight. It feels like for ever... I think we will be done after this."

And she previously told Britain's Metro newspaper, "I didn't know I was going to have two babies in two years. It's the nuttiest thing that could have ever happened to me."

But motherhood suits the Armageddon star - she told the outlet it brings her "a sense of calm".

"Having a baby and growing a baby is probably the most challenging thing that you will ever do," she added. "Then when I go to work I feel much more free in away. It's definitely changed me."
