Did Kylie Jenner just reveal some big news about Kendall?

With millions of fans following her every move on social media, Kylie Jenner knows the power of a picture… and this latest Snapchat post is very telling indeed.

The 17-year-old regularly updates her Snapchat story with updates into her everyday life, but last night she put someone else in the spotlight for a change, sharing an image of her big sister Kendall which definitely raised an eyebrow or two among fans.

The picture, which looks like it was taken outside at night, shows Kendall and singer Justin Bieber crouching on a ledge looking very shifty altogether. Kylie captioned the photo, "Oh."

Justin's face says it all, really..

Catwalk model Kendall has always been close with Justin and has long denied anything more is going on, although they have often been linked as a couple.

Just last month, Justin shared some pictures on his own Instagram feed which seemed to indicate the pair were more than friends. In the sunny snaps, Justin could be seen leaning over Kendall as she sat on the grass in a bikini, with his hands on her waist:

Rumours that something was going on began late last year, when Justin was spotted on a dinner date with Kendall just weeks before splitting from his ex Selena Gomez for the last time.

So could Jendall be a thing? Watch this space…
