Kim Kardashian has admitted her drawn-out divorce has been ''really tough'' on her.

The 'Keeping Up The Kardashians' star - who is expecting her first child with her rapper boyfriend of nine months Kanye West in early July - says she would love to be divorced from her estranged husband Kris Humphries before their baby arrives because she wants to move on with her life.

The 32-year-old reality TV star told Shade 45's 'Sway in the Morning' show: ''In a perfect world of course I would love to be divorced. It is going on its second year. And that's really tough just because I want to move on with my life.''

Kim is still legally married to basketball player Kris, who she split from in October 2011 after just 72 days of marriage because he has denied her a divorce and wants their marriage to be annulled on the basis of ''fraud''.

She said: ''I can't really speak like for him. I think the facts are I filed for divorce, he is suing me for an annulment and the only legal way to ever get annulment if there is fraud involved.

''He is claiming that I frauded [sic] him to marry him for publicity. For me, who would ever do that? It's just not who I am?''

Kim also hit back at critics who slammed her for getting pregnant before her divorce has been finalised.

She said: ''When people say things like why are you having a baby when you're married to someone else... If someone really knew all the fertility problems and the things that I was going through. God brings you things at a time when you least expect it. I am such a planner and this was just meant to be.

''What am I gonna do? Wait years to get divorced? It's such a process. Technically we are legally separated.

''He was someone that I loved a lot but you can love someone a lot and then realize they are not the right person for you. And I would have rather ended it when I felt that way then waste a year of my life not being happy. For him too.

''I knew the whole world was going to bash me. I knew that. And I said to myself, 'What is more important? My life and my happiness or what the whole world thinks about me?'

''That would be vain. That would be fake. That would be doing it for publicity. I could have stayed married.''
