Kim Kardashian Admits Being Pregnant Is Not Easy

Kim Kardashian said her sister, Kourtney, has had two easy pregnancies; however, she said that being pregnant is not as simple as she once thought.

“I wouldn’t say it’s been easy,” Kim Kardashian told ET online on New Year’s Eve, when she hosted a bash at a Las Vegas club called 1OAK.

“When people say that pregnancy is fun and they love it I would have to disagree. Even my sister [Kourtney Kardashian] has made it look easy, but it’s not as easy as people think.

"It’s a little painful, there’s a lot of growing pains. I heard it’s all worth it so I’m looking forward to that,” she added.

She and rapper Kanye West, who are expecting their first child together, rang in the New Year with a kiss as the ball dropped at midnight.

Kim Kardashian reportedly made $300,000 for her appearance at the Las Vegas club.

Dressed in a sheer black lace dress by Julien McDonald, and wearing minimal makeup, Kardashian shunned her typical-figure hugging and cleavage-baring dresses of previous years to ring in the New Year.

Her baby bump was not even visible, though she is three months pregnant and expected to give birth at the end of June.

West and Kardashian looked ecstatic all night, and the rapper often had his arms around her stomach.

While West was performing at Revel in Atlantic City, N.J., Sunday night, he made the sudden pregnancy announcement. West stopped in the middle of rapping to say “make noise for my baby mama right here,” causing the 5,000 audience members to shout and applaud.

On her blog on Monday, Kardashian confirmed West’s pregnancy announcement in a post titled "New Year, New Beginnings."

“It’s true!! Kanye and I are expecting a baby. We feel so blessed and lucky and wish that in addition to both of our families, his mom and my dad could be here to celebrate this special time with us.

"Looking forward to great new beginnings in 2013 and to starting a family. Happy New Year!!! Xo”
