Khloe Kardashian didn't know she was ''bigger'' until she started doing the family's television show.

The 'Keeping Up With The Kardashians' star has confessed she ''never knew'' she wasn't an ''ideal weight'' until she started filming the family's E! reality show.

She said: ''I never knew I wasn't an ideal weight growing up - my family never made me feel less than. We all looked different. They put me in more sports than my sisters, but I was more athletic.

''I didn't know I was bigger until I started doing our TV show, and once I was in the public eye, people were able to pick me apart. That's when I was like, 'Oh my gosh, I guess I'm chubby ... or I guess I'm bigger.'''

And the 33-year-old television personality has praised her mother Kris Jenner and her sisters Kourtney and Kim Kardashian and Kendall and Kylie Jenner for always making sure she never felt less beautiful than them.

She added: ''I really commend my mom and my sisters for never making me feel less than. Everyone always ask me, 'How do you have so much confidence?' And I'm like, 'I don't know!' I was allowed to wear the body-con dresses, the Herve Leger dresses my sisters wore.

''I didn't feel like I was too big to wear that, I was like, 'I look cute, I look good'. Granted, I should've bought a size bigger, but I looked cute.''

Meanwhile, Khloe feels there is also body shaming against thin people too and has revealed it is something her sister Kendall Jenner has had to deal with.

Speaking at a panel in SoHo ahead of the launch of her Good American brand, Khloe shared: ''But just because you're thin - there's still bullying and body shaming with skinny girls. That's how Kendall was all the time.

''I think people like to say, oh you're not plus size so you don't have a problem. But it's both ends of the spectrum, and thats what were really trying to just stop. It goes so much deeper, it affects how you are in public, how you conduct yourself going into interviews, any of that.''
