Harry Styles dons some nerdy attire for his role in One Direction's latest music video.
The boyband - comprising of Harry, Zayn Malik, Liam Payne, Louis Tomlinson and Niall Horan - recently announced upcoming track Best Song Ever.
Since the promise of the new single, the band has been releasing teasers for the accompanying music video, which sees the boys take on alter egos.
The latest development shows Harry, 19, dressed up in nerdy attire in a still from the shoot.
One Direction's official Twitter page posted a snap of the teenage heartthrob wearing a white, long-sleeved shirt and a dowdy brown sweater vest.
In true geek style, he complements the look with slicked back hair and large, round Harry Potter-style glasses.
Smart trousers and shoes finish off his polished look as he punches the air in what appears to be an office setting.
"Who's this clever-looking guy...?" the band's account teased, adding fans should check back later for a trailer of the video.
Earlier this week, bandmate Liam's character was also revealed.
The star is dressed as enthusiastic dance choreographer Leeroy, complete with a blonde wig and pink headband.
Reminiscent of '80s dance movie fame, Liam wears a baggy sweater, shorts and leg warmers as he throws some moves.
Niall's alter ego has also been unveiled, seeing him undergo an impressive transformation to emulate British businessman Lord Alan Sugar.
The Irish star looks nothing like his usual self thanks to the help of prosthetics, fake facial hair and a bulky pinstripe suit.
Zayn and Louis' personas are currently still shrouded in mystery.
Best Song Ever was due for release on July 22, but an audio version of the song was leaked early online.
