Taylor Swift posted what looked to be a very private note to social media on Tuesday.
The letter was from her arch enemy Katy Perry, who the singer has been feuding with for six years.
Swift wrote 'Thank you Katy' in red with pink hearts over the photo of the letter, and showed part of the writing.
It was difficult to see what Katy wrote but it looks like it said, 'I've being doing some reflecting on our miscommunications and though feelings between us .... would to clear the air ...deeply sorry for.'
This comes almost one year after Perry said she wanted to 'finish' their feud.
In 2014, Taylor released the single Bad Blood, which was believed to be about her feud with Katy, and the star has seemingly retaliated with single Swish Swish, which is also reportedly about their battle.
2014年泰勒发表了单曲《Bad Blood》（《敌对》），大家认为这首歌是有关她与凯蒂之间的不和的，而凯蒂似乎用单曲《Swish Swish》（《嗖嗖》）进行了反击，据报道这首歌也是有关他们之间的争斗的。
Perry said in 2017, 'Honestly, it's really like she started it and it's time for her to finish it.'
And Katy claims she 'tried to talk' to Taylor about the feud some time ago, but claims she 'wouldn't speak' to her.
Katy admits that her single Swish Swish is a direct 'reaction' to Taylor's, as she says the star has to learn about 'the law of cause and effect'.
But Katy doesn't want to fight with Taylor any longer, as she believes that women need to come together in order to 'heal the world'.
