If you've listened to Red Velvet's new song "RBB (Really Bad Boy)" even once, you'd understand how saying that the K-pop group is ending 2018 on a high note is the best pun of the year. Irene's shrill screams that ring throughout the song are the most obvious proof. Her sassy high ponytail for the music video could make a case for it, too. Red Velvet, however, has been wrapping up the year on a figurative high note, too.

"Bad Boy," the first song Red Velvet dropped this year, received major accolades. Besides being my most played song of 2018, according to my Spotify Unwrapped, "Bad Boy" was recently named the Billboard critics' pick for number one best K-pop song of the year. And out of the critics' picks for best songs of 2018, overall, "Bad Boy" ranked 43 out of 100. So I'm not the only one who has had it stuck in their head since January.

Numbers aside, the hair and makeup for "Bad Boy" was just as legendary. Seulgi's red-and-black stacked liner and Joy's neon underliner were some of my favorite K-pop beauty moments of the year. And when Red Velvet followed up its chart-topping bop with "RBB (Really Bad Boy)" on November 30, the ladies provided more looks to lust over. The music video's horror movie-inspired vignettes were punctuated by Yeri's lime-green shadow and Wendy's bold brows.

Before getting to ready to perform at year-end festivities, Red Velvet shared their favorite beauty moments of the year with Allure. They even revealed some looks they'd love to try in 2019. And if you're wondering how they got their skin glowing this year, we also chatted all about their skin-care essentials in another interview.
