Even after 17 years of marriage, actress Jada Pinkett Smith is still very smitten by actor husband Will Smith.

The 42-year-old actress is "ecstatic" about the way their union has evolved, reports contactmusic.com.

"We used to have all these rules, (but) as you go on in your relationship, you just get into a flow," she said.

She says her husband "encompasses everything" for her.

"It's almost as if calling him 'my husband' is too small of a word for what he means in my life," said the star who isn't bothered much by the rumours of the couple having an open marriage.

"I think I had a very stuck idea of what a husband looks like, what a wife should be. Once I broke all of that, a whole new world opened for me and man, oh, man, I got to see him in all his glory. And so that's what it's evolved into. And I'm just ecstatic about it," she added.
