Katy Perry appeared at The Eras Tour in Sydney to support Taylor Swift, but the audience “focused” their attention on her expression when listening to the song “Bad Blood”.

The first show of The Eras Tour in Sydney, Australia took place last night. Accor Stadium in Sydney welcomed more than 81 thousand fans in attendance. 

In addition, a number of big stars were also present at this show to support Taylor Swift , including boyfriend Travis Kelce, director Taika Waititi, singer Rita and especially Katy Perry.

Katy Perry’s appearance quickly attracted the attention of many fans, especially when Katy and Taylor were involved in unnecessary noise before. 

At that time, Katy and Taylor even did not hesitate to use music to “punish” each other.

However, all problems between Taylor and Katy were resolved, creating a memorable moment in the MV You. Need To Calm Down when Katy and Taylor shared warm hugs.

Before reconciliation, Taylor Swift is said to have used the song Bad Blood to implicitly mention Katy Perry. This makes the audience curious about Katy Perry’s reaction when hearing this song live at The Eras Tour .

 Not disappointing the audience’s expectations, vocalist Dark Horse posted a clip of his reaction when hearing this song at The Eras Tour .

In the shared clip, Katy not only (pretended) to be surprised when she heard Bad Blood, she even lip-synced along to the lyrics without missing a beat. 

This further confirms the good relationship between the two female singers at the present time. After the show ended, Katy took a souvenir photo with Taylor behind the stage.

 This is also the rare time the two have appeared together in public since their reconciliation.

After announcing her departure from the American Idol judgeship , Katy Perry was quite private about her personal and professional life. Currently, the female singer is spending most of her time taking care of her family. 

However, with their appearance at The Eras Tour , many viewers questioned whether Taylor Swift and Katy Perry will have a collaboration together in the near future.
