The couple, who have 14-month-old daughter North West, have been "walking on air" since getting married in Florence, Italy in May.

A source told PEOPLE magazine: "They're both walking on air. They're so happy.

"Kanye treats her like a princess. It's so obvious how much he cares about her, how much he loves her.

"They're meant to be together and they know it."

The pair have been forced to spend some time apart recently due to their hectic schedules, but they consider every moment they're together "precious."

The insider added: "Their be-all and end-all is just to be together as a family."

The 'Keeping Up with the Kardashians' beauty, 33, recently confirmed she and the rapper, 37, are trying to conceive a second child and she is hoping to get pregnant before her sister, Kourtney, gives birth to her third child, so they can go through the experience together.

Asked if she is planning to have another baby, she said: "I'm hoping so. You know I kind of wish I was pregnant at the same time Kourtney is. She's like more than half way in, so you know, we're trying."
