They may be the youngest members of the Kardashian-Jenner reality TV dynasty, but Kendall Jenner and Kylie Jenner witnessed their careers catapult this year.

From the sisters’ latest Pac Sun holiday collaboration launching in November to Kendall stealing the spotlight on the runway at numerous fashion shows this year, the television stars have truly stepped into their own!

Yet, their success hasn’t come without its fair share of drama. And we’ve gathered all of Kendall and Kylie’s most scandalous moments of 2014 ...

Things remained fairly quiet for the duo until May, when sources claimed they witnessed Kylie making out with her friend Jaden Smith at her sister Kim Kardashian’s wedding to Kanye West. But she quickly took to Twitter to answer questions about her and Smith’s relationship.

“Jadens a close friend of mine,” she tweeted. She then followed it up with, “Wasn’t caught making out with anyone at my sisters wedding lol.”

In June, the girls released their first book, Rebels: City of Indra: The Story of Lex and Livia, which turned out to be a total FLOP. Who says everything a Kardashian-Jenner touches is a hit!?

That same month, Kendall and Kylie hit the red carpet at the MuchMusic Video Awards in some of the most revealing outfits they have ever worn! Kendall rocked an embellished, long-sleeved white gown with slits on both legs that went all the way up to her pelvic bones. And Kylie also showed tons of skin in an orange mini dress with sheer panels!

A dinner in New York City with pals ended with a report that Kendall dined and dashed. According to magazine reports, Kendall got upset when she was denied a drink by the staff at Mercer Kitchen in NYC in August. Sources said an angry Kendall then walked out of the restaurant without paying her $60 bill.

Blaine Morris of MTV’s Skins just so happened to be the waitress for Kendall’s table. And it was reported that she chased Kendall out of the restaurant, and the reality TV star eventually threw several $20 bills in her face. “That horrible moment you chase a Kardashian down the street because she forgot to pay her bill to be thrown money in your face,” Morris tweeted following the incident. But she later switched her account to private!

Kendall was linked to bad boy Justin Bieber in September after being spotted dining with the singer in Paris.

Kylie’s fuller lips became a major conversation point for the star during the end of the summer and into the fall. Many accused her of getting lip injections or cosmetic surgery to make them bigger. However, Kylie defended herself, saying her plump pout was all the product of a makeup trick. And Kim backed up her claims!

Kylie also found herself wrapped up in a questionable “friendship” with rapper Tyga, whose ex-girlfriend Blac Chyna just so happened to be besties with Kylie’s sister Kim. The pair still claim to be just friends. But sources say the duo’s relationship is more than platonic.

In November, Kendall paid homage to the hit movie Mean Girls by reading insulting comments about herself from a burn book. She read the statements in a video posted by Dazed. And to max out the sex appeal of the dramatic reading, she did it in her undies -- because who reads a burn book fully clothed, anyways!?

In one of the sisters’ most risqué looks of the year, Kendall and Kylie hit the American Music Awards red carpet wearing dresses that showed tons of skin! And their older sister Khloe Kardashian appeared to totally approve of their saucy looks.

Toward the end of the year, there also came word that Kendall was looking to drop her momager, Kris Jenner, and seek new representation! “Kendall has made it very clear to Kris that she is no longer managing her career,” a source told RadarOnline.com.

Kylie was pulled over in November for making an illegal U-turn and for speeding while driving in Chatsworth, California, making for the teenager’s fourth driving incident of the year. In July, Kylie was pulled over by police twice in the same day! And then there was her first run-in with police back in January.

Sticking to her new skin-baring quota, Kendall initially left her mark on Christmas 2014 with a naughty video for LOVE magazine. The clip even included Kendall receiving a spanking from Santa! 

Kendall almost broke the internet herself when it was reported that she was dating Chris Brown following his breakup with his ex-girlfriend Karreuche Tran. “Chris is smitten, and Kendall’s eating it up,” a source told OK! about the pair’s budding romance.

Oh, and this flirty photo of Kendall sitting on Brown’s lap only added to the talk about the pair! Brown posted the picture of himself with Kendall, Kylie and Khloe on Instagram. But in typical Breezy fashion, he later deleted the snap.

With just a handful of days left in the year, Kendall and Kris drew a mix of hoots and head scratches when their super sexy video for LOVE's online Advent calendar was released on Dec. 23. Dressed in skimpy outfits and dancing around awkwardly, the ladies offered the Kardashian-Jenner take on holiday cheer!
