The singer is spending the week with on the show in order to promote his new self-titled album

Former One Direction singer Harry Styles has taken over James Corden’s Late Late Show for a night.
Styles was introduced as Corden on Tuesday night’s edition of the CBS talk show. He slipped into the role by telling a few jokes during an opening monologue, poking fun at two of late night comedy’s favourite targets, US President Donald Trump and Hillary Clinton.
Corden returned the favour by appearing as Styles during a skit. He later resumed hosting duties.
