Kim Kardashian - "I'm a hypocrite"

Kim Kardashian has learned a few life lessons in recent years - one of them being not everything is as black and white as it may seem from the outside.

When older sister Kourtney got pregnant with son Mason in 2009, Kim didn't approve of her sister's decision not to marry boyfriend Scott Disick.

Now, the reality star - who got pregnant by beau Kanye West while she was still legally married to Kris Humphries - says she realizes she was wrong to judge Kourtney and Scott's choices.

"I've said some things that I completely am, like, a hypocrite about now," Kim said in a clip from the upcoming special, "Ryan SeacrestWith the Kardashians: An E! News Presentation" - set to air on Sunday. "I would say things about Kourtney like, 'You cannot have a baby without being married!'"

Kim also opened up about feeling overwhelmed when she initially learned she was pregnant, when thinking about how her life would change as a mother.

"I think I'm realizing now that it really [will change my life]. I think that's why I was so anxious for awhile is just because people will say, 'Oh - your life is totally gonna change,'" she said. "Obviously you want to evolve and your life to change it will be an amazing thing, but...

"People freak me out all the time with all of their advice," she added. "Sometimes I'd rather just go through it and experience it on my own."
