Harry Styles is a protective brother

In fact, he even warned his big sis to behave herself in front of him!

You might love Harry Styles as a musician or think he’s super adorable and charming, but what we’ve just learned is that being his sibling is not a fun time.

Ch-ch-check out Harry & Co.’s hilarious concert interruption (below)!!!

In fact, he won’t let his sister date at all.

We are sure that all of the One Direction boys are going to have their fair share of success as solo artists but, when it comes down to it, it really does look like Harry Styles is going to have the most successful career of them all.

“I apologize if I seem a little distracted”, he said.

No, those worries were not his nerves for the show but his sister and her date.

And it wasn’t just their young fans who enjoyed the show – Selena Gomez, Suki Waterhouse, Bella Hadid and Stella McCartney were also in attendance.

Harry stared down at them with a faux serious face and said, “Right”.

The release follows on from the massive success of first single Drag Me Down which went to Number One on 90 iTunes charts and broke streaming records globally.

While performing on September 1 at Philadelphia’s Lincoln Financial Field, Styles motioned to bring a fan’s sign to the stage.

Oh and nice shirt, Harry.

Once he got his hands on the banner, Styles took a marker and corrected it, by adding the missing apostrophe and the “e”, so it read “you’re”.

Hours after announcing their fifth album in four years, One Direction were back on stage to begin a run of autumn dates ahead of their planned hiatus in 2016.
