We've been obsessed with One Direction's "Best Song Ever" music video ever since it came out on July 22, but now we can't stop watching Best Song Ever behind the scenes footage of the boys!

"I'm actually really nervous, we've got a lot of acting to do today," Liam says in the video.

In fact, the boys act as choreographers, marketing managers, women, and record executives throughout the course of the video!

In the music video, Zayn plays Veronica, the female assistant, complete with makeup and a long wig.

"I don't think I've drawn the short straw," Zayn says.

That's because Niall and Louis spent more than 4 hours each in makeup chairs to get their prosthetics on to look like big shot executives!

We also get a behind-the-scenes look at all of the choreography involved in the video!
