So Young, So Many Scandals! Teen Terrors Kendall & Kylie Jenner's 20 Biggest Controversies & Secrets REVEALED

Kylie caused controversy when she admitted she only has "three or four hours" of school a day in November 2013.

In yet another groan-worthy interview, Kylie bragged, “I don’t remember how it was before I was famous … I don’t know any different.”

On the November 2013 season finale of Keeping Up with the Kardashians, Kourtney kardashian accused Scott Disick of getting drunk and making a scene at Kylie's lavish August 17 birthday party. She huffed, "We're at a Sweet 16, get it together."

In October 2013, Khloe came to Kylie and Kendall's defense after fans assumed a photo of them partying at a concert was really at a club. "So sick and tired of people talking s**t about my family," she wrote on Twitter. "…Stop assuming the worst!"

The underage sisters were spotted leaving 21+ club Vignette Lounge in October 2013, looking worse for the wear.

After stories of their night out surfaced, Kendall launched a rant on Twitter claiming "no one has fake ID's and no one's partying … We're smarter than that, we have goals …"

Despite the fact that Jaden Smith is BFFs with Kylie, his dad Will Smith bashed them during an interview last May, saying "The idea of fame or exploitation or orchestrating the media is sometimes even less than desirable for us."

Kylie angered fans in New York last summer when she snubbed fans during an outing with Hailey Baldwin and Willow Smith. "People were begging for just a hello, but they didn't even look up," one source said. "A few people even started crying!"

Kylie defended older sis Kim's baby bump body last spring, insisting, "It pisses me off when people say 'You're so fat' to Kim. I'm like, 'Are you dumb?' I don't get it."

When Kendall made her catwalk debut in a sheer top at the February 2014 Marc Jacobs show, big sis Khloe was forced to come to her defense against haters. "Its a fashion show," she tweeted. "She doesn't choose what she wears. #Clueless"

During one controversial episode of KUWTK, it was revealed that 15-year-old Kendall was already on birth control. Dad Bruce Jenner flipped out, but older sis Khloe said the teen wasn't sexually active, and that her prescription was for other reasons.

Barely legal Kendall posted her first topless shot on Instagram just a few weeks after finally turning 18.

Kendall seemed to side with her dad, Bruce, after his split from Kris. She posted a picture of herself wearing a Bruce Jenner pin on Instagram as divorce drama swirled.

Biting the hand that feeds them? In August 2013, Kylie claimed that they had "10 cars of paparazzi stalking us if we drive to Malibu." Added Kendall, "These people irk me so much."

Daughters in danger? The L.A. County Department of Children and Family Services, along with police, made a welfare check to Bruce and Kris Jenner's Calabasas mansion in October 2012 after someone made an anonymous call alleging that Kendall and Kylie were in danger. Nothing was wrong, but such calls must be investigated by law

Kendall has dropped the family name professionally, hoping to avoid all association with the family when booking modeling gigs. She insists it's because using the name would give her an unfair advantage, not the opposite.

When Kendall turned 18 in November 2013, she was reportedly offered up to $1.8 million to film a sex tape like big sister Kim. She turned down all offers.
