But, it was what happened outside the concert that started getting fans' attentions...
Enter: One Directions' biggest groupies, Briana Jungwirth and her cousin Ashley Jessica. Also known as Freddie Tomlinson's family.
Ashley Snapchatted a series of photos showing herself and Briana on their way to Harry's concert, which was kind of controversial in itself given their current Louis Tomlinson sitch.
Shortly after, Ashley tweeted the following:
"I've met many 'celebs' in my life. Some are very down to earth, but after tonight, I'm appalled at how disgusting some are. So glad to me be."
Fans quickly assumed that Harry didn't allow the girls into his concert, which, as expected, sent Twitter into an absolute spin.
So was she referring to Harry? Well... not long after she received the most amount of backlash we ever did see (seriously, Harry's fans are devoted), she sent this out:
"Y'all need to stop assuming sh*t, it's annoying. I wasn't talking about Mr. Styles in my last tweet, K."
Maybe we'll never know.
