Sisters and 'Keeping Up With the Kardashians' stars Kylie Jenner and Kendall Jenner sure has a some serious bonding time together after Kylie recently posted a video of her older sister and model Kendall apparently having a victorious moment in her car while driving and even putting one leg outside the car window.

It was indeed a tricky video that many of Kylie's followers on her social media site, Snapchat were quite puzzled at what was going on between Kylie and Kendall. In the short video Kylie posted, it showed Kendall screaming, "I fixed it! I f--king fixed it!" and was very happy about whatever she fixed even placing her leg outside the window while she was on the road driving.

Of course, Kylie was on the passenger seat taking the video but the question is, how did Kendall drive like that and until now, the question remains unanswered. But what is definite is the two Kardashian-Jenner sisters are definitely still very close despite each of their blossoming careers.

Kylie has of course launched her latest Kylie Hair Kouture Extensions and has been busy with Kendall in their latest fashion line Kendall & Kylie. Kendall on the other hand has also been busy in her fast-paced modelling career taking over not only print but also on the runway.

Kendall recently also appeared on TV commercials and has been endorsing big brands like Fendi for its 2015 Fall-winter collection. Not only that, the reality star and Kylie's older sister also took over Calvin Klein's latest underwear campaign called "Original Sexy".

Kendall also recently closed the show for Chanel during the Paris Haute Couture Fashion Week. Fans definitely have to keep up with the Kardashian-Jenner family indeed as they take on their individual careers and their family businesses together by storm.
