Taylor Swift is back, and true to form the pop superstar has been unraveling an elaborate set of clues about her seventh studio album.

If you're up for a challenge, she has even hidden the title of her album in the video for ME! – which props to the Swifties, some of them have guessed correctly. But there is also the title of the second single in there, which no-one has worked out (yet).

One thing's for sure, she is having a whole lot of fun with it: "I hope I don’t seem too much like an elf under a bridge making you guess," laughed Taylor when speaking to Scott.

But the question on everybody's lips: When is the big reveal? Scott asked "When are we going to know everything about everything?"

"I’m not going to keep it a secret 'til the release, but I want a moment where I tell it all to the fans directly. I’m pretty sure I know when that is going to be, but I haven’t fully nailed it down in my mind yet. I have a couple of days I'm playing with."

There is one person, however, who knows exactly what is going down – Taylor's mum.

Tay says she bounces all her ideas off her, and no, she won't be dropping spoilers anytime soon: "I wouldn’t even have to make her swear, she just lives on a code of secrecy. That’s her main number one rule."

Scott joked how she has turned her fans into detectives and Taylor said it all started about 15 years ago, when she first put out music aged 16 and had a playful thought: "Maybe I’ll try and play a little game with them and capitalise certain letters in the lyric book, and if you were to take all those capital letters and put them together you would get a code, or it would spell out a message."
