Hendall may go down as the most talked about couple in Hollywood history.

Are they or aren't they? This is the very question that has got shippers going chaotic over for the past couple of years. There's no doubt in anyone's mind that Harry Styles and Kendall Jenner would be perfect for each other. But, do they think so?

It's been a little over a year since fans have seen Kendall and Harry interact publicly. They were actually caught canoodling on a boat over the holidays at the end of 2015 and beginning of 2016. But that fizzled out, and they haven't been caught showing that kind of PDA ever since!

The rumored on-again, off-again couple may have reunited over the weekend, though. Before anyone gets too excited, we have to look at the facts.

First things first, where could they have possibly reunited? The two bombshells attended the Kings of Leon concert! They went separately with their own group of friends, but sources are saying they sat just rows away from each other. It seems impossible for them to NOT have interacted. These two are grown, mature people who would definitely acknowledge each other in this kind of situation, right? Well, apparently not.

A source told E! News, "Harry was a few rows behind Kendall but they never spoke the entire night at all. He was dancing, singing and had a drink in his hand. He was definitely friendly and talking to people in his area and having a good time. Kendall was sitting most of the time. She was drinking water and eating popcorn and spent a lot of time on her phone."

Yikes! Did the One Direction heartthrob ignore his former lady love?!

Kendall has been spending a lot of time with another rumored boo of hers, A$AP Rocky. She could have been too focused on other things to give Hazza the time of day. Or maybe he didn't want to interfere with her night and just decided to stay away from her altogether

Regardless, this seems odd. Hopefully, there's no bad blood between the two.
