If there's ever a remake of 'Grease', Harry Styles has just made his pitch for one of the lead roles.

Considering his recent exploits on the silver screen, you wouldn't put it past the former teenybopper landing the role of Danny Zuko - particularly since he made it his Halloween costume.

Styles is currently playing a residency at Los Angeles venue The Forum, and decided to recreate the role made famous by John Travolta for Halloween, even giving a rendition of a tune from the soundtrack.

In typical Harry Styles fashion, however, he didn't sing 'Sandy' or 'Summer Nights', but 'Hopelessly Devoted to You' - a song performed by the late Olivia Newton John in the film.

Images of Newton John were also projected onto the stage's backdrop, while he and his band - dressed as Rydell High students - emerged on stage to 'You're the One That I Want'.

Watch him singing 'Hopelessly Devoted to You' below:
