Jessica Alba Shares Excitement Of Having A Son

Alba opened up about her excitement of having another addition to the family during an interview with Rachel Ray on Oct. 30, 2017.

"For me ... the girls love their dad. I wanted someone to love me more. When he comes home, they're like, 'Daddy!' It's like a party. When I come home, they're like, 'Oh, hey Mom'. I'm like, 'I do everything for you! I cook, I do all the things!'" the actress joked.

Alba is best known for her roles in Dark Angel, Fantastic Four, Honey, The Eye, Machete Kills, and Sin City. Warren and Alba met during the production of Fantastic Four. Warren is the son of former college basketball player and actor Michael Warren who starred in Hill Street Blues

In 2012, Alba co-founded the Honest Company, a consumer goods company that sells personal, baby, and household products. Alba stated that she was inspired by the birth of her first daughter, Honor, and the struggles she endured as a child to create the company.

The company, however, faced backlash after being sued for stating the infant formula was organic when it, in fact, contained 11 illegal substances.
