Hayes Alba Warren was born on New Year's Eve and Alba has described him as the "best gift to ring in the New Year".
Jessica Alba and her husband Cash Warren welcomed their third child on Sunday and appear to be going down the Kardashian route with their kids' names, with Hayes joining older sisters Honor, 9, and Haven, 6.
Alba captioned the post with: "Hayes Alba Warren 12/31/17 Best gift to ring in the New Year!! Cash and I feel so blessed. Haven and Honor are already obsessed with their new baby bro. #familyof5"
Father Cash also shared a photograph of the new born, saying: "Hayes Alba Warren: You sure know how to ring in the new year! You showed up a few days early but we couldn’t be any happier."
"Your Mamma is the strongest woman I know ... you’re so lucky to have her by your side. You have two amazing sisters who already adore you and I know you’ll be thankful to have them guide the way. On your first day of life, I promise to love you, to cherish you, and to provide you with a sandbox full of dreams to explore. Welcome to the family my sweet baby Hayes! 12/31/2017"
