How would you know if that random guy from school would turn out to be a big star later on, and will call you out for the single most embarrassing thing you've ever done to him?

That's probably what Jack Robinson thought when he got called out during a One Direction concert.

At a recent stadium gig in Oslo, USA Today reported that Harry Styles took a moment to give a shout out to a friend in the audience. And while you would love to think that a former schoolmate-turned-superstar could still remember your name, Jack Robinson probably didn't think it's as awesome when Harry told his little story.

The One Direction hunk told the audience, "I have a friend from school in the audience tonight called Jack Robinson. We are gonna get this as quiet as we possibly can and Jack Robinson is going to scream as loud as he possibly can."

And then, Harry told the crowd why he called out a friend. Laughingly, he said, "When I was about 14-years-old - I was 14 and Jack Robinson stole my girlfriend."

Of course, this led to screams from the audience. One Direction fans are among the most loyal of the lot after all, and if Jack wasn't smart enough to fear for his life right after Harry called him out for stealing his girl, he should be smart enough not to finish the show, because Harry's jab was far from over.

He proceeded on to tell the audience, " if he's still here at the end of the show, feel free - little kicks, little digs on the way out."

You never know when fans will take something like that literally. However, they did catch Jack on the big screen giving shrugs and the the universal sign of apology, so they could opt to turn the other cheek. Unless they think he's saying "what can you do about it" and he's definitely not getting out of the stadium unharmed.

Not that Harry's still bitter or anything. How could he be, when Billboard noted Harry belongs to one of the biggest pop groups int he world right now, boasting a massive, almost 25 million followers on Twitter. Not to mention he already dated and dumped one of the most powerful young celebrities in the world.

However, the first heartbreak is memorable, and Harry was able to get the last laugh, after all. Do you think his friend Jack made it out of the stadium unharmed and unscathed, or are One Direction fans feeding his carcass to the dogs?
