Taylor Swift has revealed her $300 (£226) bath time routine – featuring brands owned by her ‘nemesis’ Kim Kardashian‘s facialist and hairdresser, as well as a relatable shower staple most of us will have.

The singer, 35, unveiled gave a rare insight into her private life as she released the trailer for her new Eras Tour documentary, airing on December 12 – which featured a glimpse into her post-concert pampering.

Showcasing a selection of products on the side of a marbled bath, she could be seen using a make-up wipe to remove the remnants of her stage glamour, still clad in a glitzy bodysuit while, seemingly, in a hotel bathroom.

‘I’ll not be able to get to sleep, I can’t come down,’ she shared. ‘I just watch tons of TV, I have room service in bed, I sign a box of 2,000 CDs… and then I’m tired.

‘And then I do the whole thing again.’

Using one of Hollywood’s favourite brands, the musician had, in her inventory, Dr Barbara Sturm’s ‘Super Anti-Ageing Cleansing Cream, which retails for $100 (£95) on the site.

It promises to ‘enhance hydration levels and nourish the skin with super anti-aging actives, remove all make-up whilst protecting the skin’s delicate pH and provide anti-pollution protection and encourage the removal of fine dust particles’.

It also claims to help the regeneration of the skin barrier and aid cell renewal.

Dr Sturm became the hottest skincare guru in the 2010s, bolstered by Kim Kardashian – known to be locked in a years’-long ‘feud’ with Taylor – getting her platelet-rich plasma (PRP) facial on camera in 2013.

The reality show star is also in part credited with bringing the founder of haircare brand Ouai – Jen Atkin – into cosmetic stardom.

It’s yet another brand that featured in Taylor’s routine, with her using its $28 (£26) Body Cleanser.

Jen shot to fame for styling many celebrities, including the Kardashian and Jenners, Katy Perry, Jennifer Lopez, Chrissy Teigen, and Gigi and Bella Hadid.

Also spotted was the $88 (£84) Tata Harper Regenerating Cleanser, described as a ‘daily cleansing and exfoliating treatment that buffs and polishes for radiant, healthy looking skin’.

When it came to her haircare, Taylor opted for the Christophe Robin Paris Delicate Volumising Shampoo and Conditioner with Rose extracts – each worth $41 (£31).

In a perhaps surprisingly ordinary selection however, she used a Gillette Venus razor, which costs around $19 (£15) if purchased with refills.

Many of the brands in question appear delighted to be subtly name-dropped in the cameo, taking to their Insta story to boast of Taylor’s custom.

Dr Sturm shared a screenshot from the trailer cheekily writing ‘spotted!’, with Tata and Christophe also making their own posts.

Elsewhere, Ouai’s account, making a reference to the first track in Taylor’s latest album, joked that she was preparing ‘The Bath of Ophelia’.

On Monday, Taylor announced two docuseries charting her Eras Tour – which are set for release in just a few weeks.

The 35-year-old, who recently released her 12th studio album The Life of a Showgirl, confirmed the projects on Good Morning America.

Both of the new projects, The End of an Era docuseries and the Eras Tour Final Show, will begin streaming December 12 on Disney Plus.

The teaser for the docuseries contained behind the scenes footage of Swift’s historic tour.

‘People like to talk about phenomenons,’ she is heard saying. ‘Almost as if it was pieces falling into place. As if it just happened.

‘The Eras Tour wasn’t went all the pieces fell into place. In this tour is just when every single one of us who had done so much work, pushing, inch by inch tube where we all clicked together.

‘We have broken every single record you can break with this tour. The only thing left is to close the book. I will not be able to get to sleep. I can come down.’

‘It was the End of an Era and we knew it,’ Taylor said in a statement. ‘We wanted to remember every moment leading up to the culmination of the most important and intense chapter of our lives, so we allowed filmmakers to capture this tour and all the stories woven throughout it as it wound down.

‘And to film the final show in its entirety.’

The Eras Tour is the highest-grossing tour of all time and the first to pass $2 billion in revenue, with millions flocking to attend from all over the world.

Comprising of distinct ‘eras’ based on her ten studio albums, the singer broke an abundance of records with her three-hour-long, 40-song setlist.

The tours – with its glitz, glam and celebrity guests – saw Swift become the first ever person to be crowned a billionaire predominately from music, and the world’s richest female musician.

The impressive spectacle pulled in more than four million fans flock to arenas around the world, with A-listers, political figures and even royals all competing to be the ‘biggest Swiftie’ out there.

The Eras Tour was her sixth concert tour. It kicked off in Glendale, Arizona, on March 17, 2023, and concluded in Vancouver, Canada, on December 8, 2024.

The overwhelming demand for tickets caused Ticketmaster’s system crashed in November 2022.

She has already released Taylor Swift: The Eras Tour in October 2023, which documents the Los Angeles shows.
