The new mum took to her blog to reveal her fifth fragrance, Pure Honey.
She also unveiled the ad – a gorgeous headshot showing the reality star looking flawless.
"So excited to share that my fifth perfume, Pure Honey, is here!" she wrote on her page.
"I wanted Pure Honey to be both light and sweet but also powerfully seductive. As women we all have these dual natures.
"We can be girly and playful but also tempting and captivating at the same time. Combining the two elements was the perfect way to capture our full femininity. I created it to be delectable and crave-able, like all beautiful women are."
Explaining the scent, Kim said, "There are notes of red rose, freesia, vanilla and musk – and of course, honey."
Kim insists she oversaw the whole process of creating the fragrance. "I am super involved from start to finish," she said.
"On bottle design to ad campaign. I had this really great honey idea, so we moved away from just florals. I wanted to make sure that it had the little bee on it."
Kim's previous fragrances have included True Reflection, Glam, Gold and Signature.
The fragrance name reflects Kim's new hair colour, which she revealed last month.
"It's something she's wanted to do for a long time," her colorist George Papanikolas said. "I've been colouring her hair for a year, and she's wanted to go blonder since the day we met," he told E! Online.
He has also confirmed that Kim's partner Kanye West is a big fan. "He loves it! He was a big cheerleader for her to go blond".
The queen of reality TV recently shared a photo on Instagram of her and Kanye's night out with Oprah Winfrey and rapper P Diddy.
"Oh no big deal," wrote Kim alongside the photo, which thousands of her fans "liked".
