Kim Kardashian West ''hopes'' Kanye West will ''help out'' during her pregnancy.

The 'Keeping Up With the Kardashians' star and her 37-year-old husband are expecting their second child together and the brunette beauty wants the 'All Day' rapper - with who she has 23-month-old daughter North - to take more responsibility this time around.

Asked if Kanye will help her out during her pregnancy, she said: ''I hope he will! He didn't help me last time. He did after, he was like 'OK, I can't take this I'm going to help you.' But we also like to keep everything really separate because it's just sometimes easier that way.''

Though the couple have explained to North that she will be getting a sibling, the little girl doesn't fully understand.

Kim told Us Weekly magazine: ''She knows that Mommy has a baby in her belly, but she thinks everyone has a baby in their belly. I think she thinks its my belly button.''

The 34-year-old star gained a lot of weight while pregnant with North and has vowed not to do the same this time around.

She said: ''This time around I have a nutritionist to keep me healthy while I'm pregnant.

''The last pregnancy, I ate a donut every single day, I'm not doing that this time. But I've also been taking it easy and enjoying myself.''
