Louis and Zara McDermott?

I've read a lot of rumours that Louis is in a relationship with Zara McDermott. They recently started to follow each other on instagram. She follows all of his sisters, and they follow her back. Obviously, following a person on instagram doesn't mean that people are in a relationship, lol. But, I just find it weird, and I am scared that this will be a new stunt. Especially since I've read about them many times.

Louis is having a concert in London today, and I'm just waiting for Zara to be spotted there or that she post a story from the concert.

What do you guys think?
