It's hard to un-see this video after you've seen One Direction's new music video of 'Best Song Ever.'

While clips of the Best Song Ever video had been leaked in the prior week, One Direction released the full shocking product Monday.

Every one of the five members of the English-Irish boy band transformed into someone else in the music industry. The acting was superb, and mentions of Angelina Jolie were heard in a Hollywood office.

Taking roles as both themselves and their alter-egos in the video, 'Best Song Ever' showed Zayn Malik embrace his inner goddess. He (or maybe I should say she) sported a white blouse and a black skirt. (The white blouse showed his fake cleavage. Full makeup, a brunette wig, and large spectacles, made him almost unrecognizable as a sexy secretary.

In their best american accents, Niall Horan and Louis Tomlinson, welcomed the pop group, dressed as studio executives Jonny and Harvey.

Harry dresses up in geeky glasses and plays 'Marcel the marketing guy.' The short 'Best Song Ever' film however also showsHarry flirting with the secretary as himself (not Marcel).

Liam Payne dressed up as 'Leeroy the choreographer' in a red bandana, strawberry blonde hair, in a grey sweatshirt with jeans.

The hilarious short was reportedly penned by James Corden. In addition to the office meeting, we also see the group bashing up the building, and a choreographed dance in the cafeteria.
