Congratulations are in order for Liv Tyler and David Gardner.

The Leftovers star, 37, and her sports manager/agent beau welcomed a son on Wednesday (February 11), PEOPLE reports.

“He’s healthy and everyone is very happy,” the rep tells the mag. That said, a source says the baby boy arrived six and a half weeks early and will need to remain in the hospital for some time.

The newborn – whose name has not been revealed – joins big brothers Milo, 10, and Gray, 7, the couple’s children from previous marriages.

The actress recently opened up about her second pregnancy.

“I mean, for seven years I’d been saying I wanted to do an HBO show with an ensemble cast. And I wanted a house in the country,” Tyler shared. “And getting to have another child? If you knew me well, they were the things my heart longed for. And they all came together, like a speeding freight train, in one year.”
