One Direction FINALLY premiere full video for new single Best Song Ever - watch

One Direction have FINALLY premiered the full video for new single Best Song Ever.

The cheeky 1D chaps have undergone some amazing transformations lately and last week each band member showed off their new looks by revealing the characters they play in the video.

But THE TIME HAS COME - you can now watch the video in full, which, lets face it, is pretty exciting stuff.

In the promo Harry Styles, Liam Payne, Niall Horan, Louis Tomlinson and Zayn Malik play different characters including studio executives and choreographers who are assigned to work on their new video.

The single - the first off their highly anticipated third studio album - was number one in the iTunes charts for 61 countries within just 12 hours of being available to download.

For his video Best Song Ever video transformation Zayn underwent a drastic makeover to become sexy secretary Veronica.

The relatively shy Zayn wore a long black wig and blue blouse to portray the character who hands out drinks in the video.

Harry, meanwhile, was transformed in a marketing boss called Marcel.

The 19-year-old heart-throb, who is usually seen in trendy blazers, wore a tank top and a pair of nerdy glasses.

With the curly hair that helped make him a household name straightened and slicked back, he ended up looking like Sir Cliff Richard in his pomp.

Liam, also 19, was given the role of a choreographer named Leeroy. He had to wear a pink headband and blonde wig.

Louis, 21, became a record company executive called Johnny – and had to hide away his locks for a bald look.

Niall, 19, had to wear padding underneath his shirt to play rotund boss Harvey.

He was also given a fuzzy ginger beard by the band’s talented make-up artists.

Best Song Ever will be the first single released off the band’s third album, which is due out in the autumn. The song is also featured on the trailer for their movie, This Is Us, which is out on August 30.

A source close to the group said they chose the music ­industry theme because they like to keep their loyal fans entertained by doing something different.

The insider said: “The boys had a great time making the movie.

“They couldn’t ­believe how different they look. They can’t wait for their fans to see them looking like this, they think they will find it absolutely hilarious.
