The former One Direction star caught him just in time when he walked in the iconic Studio 8H with Kenan Thompson and watched the whole thing getting unfold.

When Hernandez noticed them, he quickly tried to come clean explain, "I thought you weren’t coming, so I thought I would just go on as your understudy."

Sign of the Times crooner revealed that he was only 15 minutes late because he and Thompson went out for a couple of pain au chocolats, "a tradition when I host."

The As It Was singer then took the stage announcing "see you on Saturday."

This is not the first time Styles will be appearing at the show. He has been there a several times as musical guest and will mark his second time as a host.
