Kim Kardashian is finding out quickly that pregnancy isn't as easy as she thought it was going to be.

While attending a NYE party at 1 Oak Nightclub at The Mirage in Vegas, the 32-year-old reality star said the following to ET:

    "I wouldn't say it's been easy. When people say that pregnancy is fun and they love it I would have to disagree. ... Even my sister has made it look easy, but it's not as easy as people think. ... I heard it's all worth it so I'm looking forward to that."

The gorgeous mom-to-be, wearing a sexy lace dress by Julien MacDonald, adds that she's been taking lots of naps.
