North West is just that naturally beautiful. After Kim Kardashian shared a close-up picture of her daughter's gorgeous face via Instagram on Monday, Dec. 16, some commenters took note of the 6-month-old little girl's perfectly shaped eyebrows and then wondered whether they had been waxed or groomed by the tyke's mom -- a suggestion Kardashian slammed as "sick."

"Do people really think I would wax my daughter's eyebrows so young?" the first-time mom asked via Twitter on Tuesday, Dec. 17. "Come on, I'd wait until she's at least 2 1/2!"

A minute later, she added: "I'm kidding!!! It's pretty sick for people to insinuate that I would wax my daughter's eyebrows. They are thick, natural, and amazing!"

(Another reality star, Teen Mom's Farrah Abraham, apparently felt differently about her own daughter's eyebrows. She admitted earlier this year to waxing 3-year-old Sophia's arches while the little girl was sleeping.)

Kardashian first posted the new photo of North on Monday afternoon, captioning it simply "SMILE." Earlier in the day, she had been answering questions about her daughter on the social networking site Mobio Insider.

Asked her favorite thing about North, Kanye West's fiancee replied: "It's really hard to choose, but her baby smell and her laugh!"

Motherhood "completely changed my life," the 33-year-old replied to another fan. "You have a different set of proprieties. Nothing matters except your brand new family."
