Justin Bieber's ex-girlfriends are certainly wasting no time to prove their fine without him. While Kendall Jenner shared a video of her sexy dance moves, Selena Gomez stripped down to a yellow bikini showing off her cleavage. Yet, between the two posts, who's the hotter Instagram babe?

Despite her embarrassing fail at the Billboard Music Awards, Kendall Jenner is moving on from the One Direction - 5 SOS flub. In fact, thanks to her 10 million followers on Instagram, Kendall couldn't care any less about the Twitter hate hash tag #Kendallyouhadonejob. To celebrate having gained 10 whopping million followers on the social networking site, the model shared a sexy video of her dance moves.

"10 million insta followers?! soooo much love!!! @robscheppy @thescottycunha," stated Jenner. Check out the Instagram video below.

On the other hand, Selena Gomez has also showed off her sultry side on Instagram. The "Come & Get It" singer stripped down to a yellow bikini which showed off her voluptuous figure and cleavage. Check out the post below.

"Taking my power back.. can't wait to show you where I've been. I love y'all. Ps, I still obsess over pickles," captioned Gomez on the photo.

The sexy selfie shows that Gomez is obviously happy despite the tumultuous months. Gomez had been involved in a number of rumours involving her messy and toxic reunion with Justin Bieber. However, it seems her reunion with BFF Taylor Swift and Jennifer Aniston's advice has got the Latina thinking straight.

Putting aside the Justin Bieber and "Jelena" drama, who between Kendall and Selena's Instagram posts - both shows their sexy and sultry side - which is hotter? Kendall's sexy dance moves at her Paris hotel or Selena's beach selfie showing off her cleavage?
