While many families have some kind of small, healthy rivalry between siblings, a new report suggests that there's one between Kim Kardashian West and little sis Kylie Jenner that is starting to heat up.

According to Hollywood Life, Kim's new contour and highlighting kits that she launched to great success are causing Kylie to feel slighted, and driving a wedge between the family.

A source said, "Kylie is really upset. She feels like it's a slap in the face from her own big sister."

Apparently, the rivalry has existed in some way for a long time, but the source said, "It heated up when Kylie became more famous than Kim on Instagram."

It's a little surprising to hear that the ladies are potentially seeing each other as bitter rivals since they've partnered together on projects in the past.

Back in April, Kylie announced a partnership with Kim for her Kylie Cosmetics line and when that collection debuted it sold out very quickly.

However, the source added, "Deep down Kim is very competitive with all of her sisters, despite frequently helping them with their business ventures!"

Last year, Kylie's Lip Kit line came under some pretty steep controversy for receiving an F with the Better Business Bureau. This was due to customers complaining about the product.

Not one to take it lying down, Kylie quickly fired back, "I'm sick and tired of people coming for my business. I love everything about Kylie's Cosmetics and I will do anything in my power to protect and improve it every day and make you guys happy,"

She added, "I don't want to respond to the haters but you guys deserve an answer and to know the facts. I love you and apologize to anyone who felt the urge to complain and didn't receive the service they deserve."

Continuing, Kylie said, "You guys are the reason I keep going and I'm motivated every day to make Kylie Cosmetics the best it can be. I'm continuing to learn and I just want to make everyone happy."

Finally, she ended, "Because so many of you spoke out, I'm excited to tell you that the Better Business Bureau has looked at the facts and changed the rating."
