Fans first learned back in July that Alba was expanding her family. In an Instagram post, the actress posed with her daughters for a boomerang while holding a giant No. 3 balloon.
Most recently, the businesswoman received a special baby shower from her closest friends including Rachel Zoe and Molly Sims at Laduré in Beverly Hills.

"She is very healthy and her daughters are so excited to have a boy come into the family. They keep calling the baby the 'Christmas miracle,'" our source shared. "Jessica has been working her entire pregnancy and will still play a role when the baby is born. Her company means a lot to her but she is thankful that she has a great team to help her."
