Katie Holmes is telling the new issue of In Style that her marriage to Tom Cruise has completed her.

"I try every day to let him know how much I love him," Katie says of her husband of one year. "It gets better and better. It has made my life."

Calling her love with Tom, 43, "all-encompassing," Katie, who turns 29 next week, says falling for her superstar husband was easy.

"It happened quickly, but I was certain it was what I wanted," she says. "I never felt overwhelmed. I thought, Okay, good. Here we go."

In just two years, Katie became a wife and mother. When Suri was born last year, Tom was "by my side the whole time. I couldn't have asked for a more supportive human being. He had the room ready, candles everywhere, pictures in frames. It was very homey and beautiful."

Now Suri is "talking up a storm, running around, so aware," she says. "She loves coloring and creating. She's a great mimic and dancer. She came to the photo shoot and was all into the shoes."

So are more kids in the future?

She'd "love to," says Katie, but "I'm in no particular rush."
