Todrick Hall, who is an internet sensation in his own right and will be familiar to anyone who’s seen RuPaul’s Drag Race, appeared behind Taylor in the scene with the infamous “I [Heart] T.S.” t-shirts.
Speaking to INSTANT, he refrained from going into too much detail about Taylor herself but did tellingly allude to her characer when he said: “I think it speaks volumes of what type of a person Taylor is as a human being, as an artist, that she was able to get all these people on a set, shoot an epic … and get them to not say anything.
“People just really were excited and I was more excited to see the reaction of people online than to tell people.
“So I didn’t even tell people that were very, very close to me; my own family didn’t know.”
The video was allegedly filmed way back in May, but Hall said he could relate to Swift’s desire to keep everything under the hat.
“It was the hardest secret ever to keep, but I know how I am as an artist and when I’m creating stuff, even if it’s just on my YouTube channel, I don’t want anyone to tell anything, I don’t want anybody to post a Snapchat or a picture,” he reasoned.
Look What You Made Me Do smashed Adele’s record for most video views in its first 24-hour period, following its release at the MTV VMAs on Sunday.
The song is also due to give Swift her first ever UK Number 1 single on Friday.
The star has previously peaked at No2 in this country three times: with Love Story, I Knew You Were Trouble and Shake It Off.
Look What You Made Me Do is the first single from her new album Reputation, which is due out on November 10.
Tour dates are expected to be announced in the near future.
