Hearing about siblings arguing or getting into small fights is nothing new. When your family's disagreements are publicly broadcast for millions of viewers to see, that's when things can get a little ugly. On the season 11 debut of Keeping Up With the Kardashians, Kendall Jenner is seen calling her younger sister Kylie a "b***h" and a "c**t." Fans worried there was a possible strain on their relationship, but Kendall quickly took to her personal website to defend her bond with her sister, stating they're still best friends.

On Sunday (Nov. 15) the Kardashians and Jenner dynasty kicked off their 11th season of KUWTK and it was filled with a lot of drama. One of the most talked about scenes included the sisters arguing over clothing as they prepared to attend the 2015 ESPY's, where their father, Caitlyn Jenner, was being honored with the Arthur Ashe Courage Award.

The 20-year-old model tried to borrow one of Kylie's favorite dresses without asking her and things went sour once Kylie told her she wasn't allowed to wear it. The two were getting dressed at Kylie's house, so Kendall assumed she could take an alternate outfit with her for after the award show. The-18-year-old, who's gained quite a following from a unique and risky fashion choices, refused to let her wear the brown dress.

Once Kendall realized her sister wasn't going to change her mind, that's when the derogatory names began to spill out of her mouth. Kendall reflected on their relationship growing up and explained why fans shouldn't take their verbal fight so seriously.

"It's funny - growing up, Kylie and I were the terrible twosome!" Kendall wrote on her website according to People. "We were so rebellious and adventurous. We would run around all day long and just do stupid things with each other. I couldn't imagine growing up any other way. It was awesome having someone so close in age to me - we could relate to one another."

Siblings are bound to push your buttons every once-in-a-while, but the 2015 Victoria's Secret Fashion Show model revealed there were times when their arguments turned into bad physical altercations. Despite not always seeing eye-to-eye, Kendall admits Kylie is her best friend.

"We've always remained close, but over the years the two of us have just matured," Kendall wrote. "We've really kind of found our own identities, which I think was important to us both. For years we were really stuck as a duo and now we've truly become our own people."

While she urges fans not to worry, more drama ensues on KUWTK. In the season promo trailer, Kendall doesn't agree with Kylie bringing her older boyfriend, Tyga, on a trip or the choices she's been making in life. To see how it all goes down, catch KUWTK on Sundays at 9 p.m. EST on E! Network.
