Khloe Kardashian wants to have children but only if she stays slim.

The socialite says her pregnant sister Kourtney Kardashian has inspired her to want to start a family with new husband Lamar Odom but after working hard to lose weight, admits she would be worried about the toll it would take on her figure.

She said: "Honestly, I just lost weight I want to be a skinny pregnant person, like how my sister Kourtney looks so cute pregnant. I can't be a house after I just lost weight."

Although she is happy with her shape, Khloe thinks her critics will always make cruel comments about her body.

She said: "Well, I am always fat no matter how much weight I lose. It's like I can never have a good body. But I have a really strong sense of self-esteem.

"It kind of frustrates me because I do work really hard. I eat really well and I try to look the best I can."

However, Khloe insists she doesn't worry about her size but thinks she would be more concerned if she didn't have her family for support.

She explained to E! Online: "Growing up in Hollywood, we definitely had friends who were obsessed with being skinny, but that's not really what we're about. We just want to be in our best shape.

"We are all curvy and we are all accepting of our body types. I think if I was in Hollywood by myself, I would be so much more susceptible to falling into having an eating disorder."
