Interestingly, when The Fall Guy actor hosted the NBC comedy show the weekend before, the Sign of The Times singer was sitting in the audience.

“Is that Harry Styles?” Gosling quipped. “What are you doing here, man?”

“Well, I’m hosting next week and it’s been a while, so I just wanted to watch, get a feel for it,” Styles, 32, responded.

Shortly before Styles returned to studio 8H for hosting and as musical guest, a celebrity gossip account DeuxMoi shared on Instagram that he is expected to invite a surprise guest.

However, when the episode aired 1D fans’ hopes shattered once again.
