Jessica Alba believes her husband Cash Warren is her soulmate.

The 31-year-old actress says she felt a kindred connection when she met her producer husband on the set of 'Fantastic Four' in 2004 and instantly knew they would stay together forever.

She said: "I just knew when I met him that I was going to know him forever. It was weird; he instantly felt like family. I'd never felt like that with anyone. We got each other. We're kindred spirits."

Jessica has daughters Honor, four, and 16-month-old Haven with Cash after tying the knot in 2008, but although their love is still strong, her notion of romance has changed over time.

She said: "On a weekend Cash might say, 'Go get your nails done with a girlfriend. Haven is down for a nap and Honor and I will play. I know you work hard. You deserve some time for yourself.'

"That, to me, is romantic. He's saying, 'You matter,' and that I'm more than just the mother of the kids or the wife who goes out to events with him."

Nothing is more important than family for the 'Sin City' star and the home bird admits photographs of their close relatives take pride of place in their Los Angeles abode as they want their two daughters to learn the value of family.

Jessica added in an interview with the new issue of InStyle magazine: "When Cash and I moved into our family house, we collected hundreds of pictures of our aunties, great aunties, moms and dads, grandmas and grandpas, and sisters and brothers. Then we mounted them in the foyer of our home, covering the wall from top to bottom. Our daughters are continually reminded of where they come from." - Bang ShowBiz
