Sisters are supposed to support each other, not tear each other down! Kendall Jenner and Kylie Jenner both grew up right before our eyes on their family's long-running reality TV series Keeping Up With the Kardashians and they've each blossomed into young women with their own respective careers — with Kylie building her own lip kit empire at 20 years old while Kendall, 21, is one of the top models in the fashion industry. But according to a new report, Kylie wants to prove to her sister that she's not the only one in the family who has what it takes to walk the runway.

“Kylie has never understood the big fuss about Kendall and her catwalk career. In her opinion, she has just as much to offer in the beauty and style stakes," a source revealed to Radar Online. Ever since Kendall started walking the runway and landing coveted fashion magazine covers, she's had a "superior attitude" and Kylie is “fed up."

“She intends to wipe that smirk off her face and has instructed her agents to contact all the main booking and scouting companies,” the source continued, “plus she’s networking like crazy in the same business circles as her sister.”

KUWTK fans will remember that the moment their rivalry over modeling began was captured in a previous season of the series. In a clip from an older episode, a 14-year-old Kendall presented her mom, Kris Jenner, with a collection of photos of herself and revealed that she was serious about wanting to start a career in modeling. Kris told her daughter that she’ll make some phone calls — and Kylie had a mini-meltdown.

“If you want to help her model, you can help her model,” she told her mom. “But it’s just gonna get to her head and all of us are going to be in her little throne path and listening to her. We’re gonna be like, ‘Oh my god, you’re right — you’re like the coolest in the family ‘cause you model when you’re 14.”
