Jessica Alba and Cash Warren Welcome a Baby Boy on New Year's Eve

Jessica Alba and Cash Warren have a new addition to their family! The couple, who are already parents to daughters Honor and Haven, welcomed a baby boy on Dec. 31. "Hayes Alba Warren 12/31/17 Best gift to ring in the New Year!!" Jessica wrote alongside a precious photo of their newborn. "Cash and I feel so blessed. Haven and Honor are already obsessed with their new baby bro. 👶🏽💙 #familyof5."

The Honest Company founder first announced that she was expecting in July when she posted a sweet video of her daughters holding up numbered balloons. She later revealed the sex in a similar fashion by opening a box filled with blue balloons and confetti. Aside from showing off her growing belly during the annual Baby2Baby Gala with her husband in November, Jessica also had a star-studded baby shower last month to celebrate the arrival of her little one. Congrats to the happy couple!
