If this girl wasn't a Directioner before, she definitely is now! When Harry Styles saw a grumpy tweet about One Direction's upcoming movie, This Is Us, he didn't just ignore it -- he responded in the funniest way possible! And, we're thinking this girl's mouth dropped open.
In later tweets, she admitted she loved him and was just having a bad day, so we're sure Harry's response cheered her right up!
What would you do if Harry tweeted you? Let us know in the comments!
