Kylie Jenner took to social media late Monday night to not only show off her sexy curves with a racy selfie, but also tease one of the new colors she'll be adding to her Lip Kit By Kylie collection.

A few weeks ago, the 18-year-old reality star announced that she would be dropping three new colors for a Valentine's Day collection of her popular - and sold out - Lip Kit with a "new very exclusive formula." Just hours later, she revealed the first exclusive color, Posie K, but since then, all we've seen are black and white shots of the new formulas being made. But last night, Jenner finally revealed the second color of the highly anticipated collection in a series of Snapchat videos, and one very sexy Instagram selfie.

"Could this be a new lip kit color? ;)" she captioned the seductive photo of herself behind-the-scenes at a photo shoot in a revealing bright red bra, panties and matching matte lip. She's rocking Huit Lingerie, specifically the French Muse Padded Bra and String Bikini Bottom.

She then uploaded a video of herself in a tight red leather tube top dress, still rocking the scarlet hue on her lips, and tagged her Lip Kit's official Instagram account in the caption. She also posted a few videos from the photo shoot, and confirmed that this new shade is definitely going to be a part of the Valentine's Day Collection.

"I had Lip Kit photo shoot today and this is one of my new colors," she said on Snapchat. "It's red and it's pretty bomb."

This new red shade, which does not yet have a name, and Posie K will hopefully be released soon as Valentine's Day is just around the corner. She will also be restocking the original three shades: Candy K, Dolce K and True Brown K, which sold out in just seconds during their first two releases.
