Jessica Alba knew she was going to marry her husband the first time she met him.

The actress felt an instant connection with Cash Warren - who she tied the knot with in May 2008, shortly before she gave birth to their daughter Honor Marie - and had to call her pal to let them know she had found her 'Mr. Right'.

She explained: "Right after I met Cash, I called my best friend and was like, 'I met this guy and I feel like I've known him forever and I'm gonna know him for the rest of my life!' "

Despite their instant chemistry, Jessica insists it is crucial to work at your relationship and says being a team is far more important than being romantic.

She added to the US edition of Cosmopolitan magazine: "The romantic stuff comes and goes, but it's like, does that person have your back? You have to be a team navigating through wherever life may lead you and I want a friend for that."

The 'Sin City' star - whose daughter Honor is now two - recently revealed she plans to adopt a child with Cash in the future.

She said: "My mom grew up around a huge family, and they always wanted more kids, and I was like, 'Why don't you just adopt?'

"I'm totally inspired. If you have the love, and the capacity to love children, you should just adopt. And I plan on doing it."
