Everyone, meet Lula Rose!
The little beauty with the pretty name is the newborn daughter of Liv Tyler, 39, and her fiancé, British sports agent David Gardner, 38.
The actress revealed the happy news by sharing a sweet photo of Gardner cradling his little girl on Instagram late Sunday.
"Hello!!!!! Our beautiful baby girl is here !!!! Lula Rose Gardner We are sooooo happy. Heart exploding with love!!!!!" Tyler captioned the precious photo, peppering it with heart emojis.
Gardner also shared the adorable pic — which is especially tender since it shows him wearing one of Tyler's silky monogrammed pajama tops.
"Our gorgeous baby girl has arrived 'Lula Rose Gardner' unbelievably beautiful, healthy and thank goodness she looks like her Momma!!!! Truly blessed. Daddy’s girl," Gardner wrote.
Lula Rose is baby No. 2 for the couple, who are already having a ball with their 17-month-old son, Sailor.
Tyler (whose dad is Aerosmith rocker Steven Tyler) also has a son named Milo, 11, with British musician Royston Langdon, while Gardner has a son, Gray, 8, from his marriage to British actress Davinia Taylor.
The couple have been documenting Tyler's pregnancy since her ecstatic baby announcement back in January.
Just weeks ago, the actress shared a photo of herself and joked about her "pointy" baby bump, exclaiming, "I can't wait to meet the beautiful little human living in there."
And now she's here!
Congrats to mom and dad, and welcome to the world, little Lula Rose!
