Jessica Alba's youngest daughter can't wait to have a baby brother.

The 'Sin City: A Dame To Kill For' star is expecting her third child - a son - with her husband Cash Warren and no one is more pleased about that then their six-year-old daughter Haven.

Speaking in an upcoming episode of The Rachael Ray Show, Jessica said: ''My six year old, she was worried about being a middle child, but she gets to be a big sister and a little sister. So, she's stoked about that - and she doesn't have to compete with another girl ...

''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!'''

Meanwhile, the 36-year-old actress - who also has nine-year-old daughter Honor with Cash - revealed she was expecting a boy in a sweet Instagram clip with her daughters. The trio tugged on a string, which was attached to a box and blue confetti fell down onto them.

Jessica captioned it: ''@cash_warren and I couldn't be more thrilled to announce... #officiallyoutnumbered #babyboy #cantwaittospoilhim #hugsandkissesforlife #soontobemamaofthree (sic)''

The brunette beauty previously revealed she works really hard to maintain a balance between her work life and family life.

She shared: ''I think it's the quality of time that you put in at work and how you're fed at work and what you bring home. And also what you let go of when you come home. A happy work place actually makes for a healthier person and healthier children. If you work five hours a day but you hate your job, your attitude when you come home and what that imposes on your kids outlook and their life and their relationship with them, it actually really affects it. But if you're happy - even if you come home late and you're working long hours - if they see that you're happy and you're in a good mood and you're present with them that's way better than you spending ten hours a day with them in misery.''
