Kylie Jenner and Kim Kardashian are collaborating amid jealousy rumors.

Kardashian and Jenner decided to work together for the new collection of Kardashian’s KKW Fragrance perfume. Jenner announced this on Instagram. According to her, she loves Kardashian’s perfume even before they decided to work together.

“Soo I did a collaboration with @kkwfragrance and i couldn’t be more excited, wow,” Jenner wrote.

“I’ve fallen in love with my sisters fragrances and it’s all I’ve genuinely worn since i could remember! Being able to create 3 of my own is a dream!! Can’t wait for you guys to get your hands on these August 23rd Thank you Kim @kimkardashian.”

There will be three vibrant lip-shaped 30 ml bottles of perfumes named after Jenner for $40 each in red, pink and nude bottles. The products will be launched on Friday at 12 p.m. PST at KKWFRAGRANCE.COM. The shape of the bottles was a nod to Jenner’s iconic Kylie Cosmetics Lip Kits.

Kardashian told her fans that each fragrance is uniquely different. The “Keeping Up With the Kardashians” star said that each one is “so juicy, I don’t have any other words.”

Jenner and Kardashian are reigning over the beauty world with their brands. Jenner owns Kylie Cosmetics and Kylie Skin. Meanwhile, Kardashian owns KKW Beauty and KKW Fragrances.

Aside from their businesses, the siblings were often pitted against each other due to their Instagram posts. Jenner once shared a snap of her sporting an all-black outfit with short hair. However, some netizens noticed that the way she styled her hair was similar to how Kardashian did hers days before she uploaded the photo. There were speculations that Jenner’s been copying Kardashian.

However, the two celebrities did not mind the jealousy rumors. Instead, Kardashian and Jenner ended the speculations by wearing matching outfits to celebrate National Sister Day. Kardashian shared the snap on Instagram along with more photos of their three other sisters Kendall Jenner, Kourtney Kardashian and Khloe Kardashian.

“Not sure what I would do without them!!!! #HappyNationalSisterDay,” Kardashian wrote on the caption.
