Jessica Alba thinks she has the ''best husband in the world''.

The 'Sin City' actress says she wouldn't be able to juggle her film career, eco-friendly baby products line, new lifestyle book and raising daughters Honor, five, and HAven, two, if it wasn't for the support of her spouse Cash Warren.

She said: ''Cash is the best husband in the world. I wouldn't have been able to keep my company going and do the book if I didn't have him there for me and help with the children.

''He's always very considerate and understanding of who I am and my goals. We complement each other very well.''

Despite their busy schedules, Jessica and Cash always make sure they have time for date nights as they believe they are vital to making their marriage work.

She told Britain's OK! magazine : ''We make sure we have enough time to be together where we can shut out the world. My parents are always coming over so Cash and I can go out on the town or I'll make a special dinner for us.

''Those are the moments that are special and important when you're a couple raising young children together and so much of your time revolves around getting your kids dressed, feeding them, getting them ready for school and into bed. It's important to have nights for yourself.''
