The 37-year-old reality star counted down to the new year with her friends and family, including husband Kanye West, and just as the clock struck 12, Kim grabbed her guy and gave him a big celebratory smooch.
The mother of two was sure to record the moment, and when Kanye hesitated at first to give her a kiss while she was still on Snapchat, she exclaimed, "Don't leave me hangin'!"
The power couple also posed for photos, which showcased their stylish ensembles. Kanye sported a dark plaid shirt, black jeans and white sneakers, while Kim wore a figure-hugging, off-the-shoulder white dress and heels.
While she was still rocking blonde hair on New Year's Eve, Kim teased on Monday that she might be going back to brown. Sharing a flashback photo on Instagram of when she was brunette, she wrote: "Dark hair for the new year?"
She later posted: "I hope everyone has a [sparkly] new year!"
Kim also shared on Instagram that a highlight from 2017 was starting her own makeup line, KKW Beauty. In June, she spoke exclusively with ET about her new products, and how she hopes her and Kanye's work ethic rubs off on daughter North and son Saint. Check it out:
