One Direction New Single 2013 'Best Song Ever' Trailers Introuduce Liam Payne, Niall Horan Characters: More Debuts to Come Before June 22 Release Date

One Direction are really hyping up the release of their new song and music video "Best Song Ever." Though, with a title like that, they almost have to. After holding fan contests for cover artwork, lyrics and more, the British boy band has started releasing trailers for the upcoming clip.

Yesterday (July 16), the "Makes You Beautiful" group posted the first trailer teasing the concept for their new video. "Best Song Ever (6 Days to go)" features band member Niall Horan looking completely unrecognizable as "Harvey, The Studio Exec." "Will Smith? Tell him I'll call him back!" he screams in a grumpy old man voice.

Today's clip, fittingly titled "Best Song Ever (5 days to go) shows Liam Payne taking a turn as "Leeroy, The Choreographer." Donning an old school sweatshirt, pink sweatband and too-high socks, the singer hams it up for the camera.

Surely, fans can expect a new teaser trailer each day, with Harry, Zayn and Louis' characters all making their debuts.

The videos have done well pumping fans up for the song's release thus far. Day 6 has received over 1 million views in a single day.

The music video for "Best Song Ever," which will debut along with the song on Monday, July 22, seems as though it will be a hilarious take on the process of writing a song and making a video. Characters like "the director," "the makeup artist" or "the writer" are likely to pop up.

"Best Song Ever" was first debuted in the trailer for the upcoming One Direction concert film This Is Us. That movie will premiere in theatres on Aug. 30.
