Taylor Swift revealed how she managed to fit in The Tortured Poets Department set ‘halfway through’ her Eras Tour.

In her newly released Eras Tour Book, the 34-year-old megastar got candid with Swifties about squeezing in an eleventh era filled with dazzling new ensembles and daring choreography for the remaining 70+ stops on her concert tour at the time.

‘We conceptualized and rehearsed it secretly, and surprised the Paris crowd with it when we started our European leg of the tour,’ she penned in the 256 page picture book.

The Mirrorball hitmaker also detailed wanting to maintain a ‘minimalist, white, stark and bold’ theme for TTPD set, a major contrast from her rest of the colourful.

‘There was nothing else in the show like it, and it was such an exciting challenge to try to improve upon a show I already loved,’ she added.

The Eras Tour Book was released exclusively at Target, which was made available in stores on Friday and online on Saturday — it retails for $39.99.

‘So, there was only one conclusion for how to kick off this last leg, and that is Miami, Florida!’
