Taylor took to the stage at Sydney's Accor Stadium four nights in a row from Friday until Monday after three epic sell-out shows in Melbourne 

Returning the following evening, Toni was then seen spending time with fellow actress and comedian Rebel Wilson. 

Rebel took to Instagram to share a gallery of snaps with her family and friends at the concert, and a grinning photo with Toni.

The Sixth Sense star Toni beamed from ear-to-ear as he wrapped her arm around Rebel, 43, for the picture as they posed with the stage in the background.

Toni also shared a video of herself walking through the stadium as Taylor performed, alongside the caption: 'Thank you @taylorswift you merry maker #sydneynight2.'

She then confirmed she had returned for Taylor's third performance at the Accor Stadium in an impressive back-to-back attendance.

The Hereditary actress shared a video of herself walking into the stadium halfway through the show while Taylor belted out Shake It Off.

Making reference to her three-day run of shows, Toni captioned the post: '@taylorswift #ERASTOUR Sydney - Night 3 #shakeitoff #yesthatisallmyhair.'

It is not known whether Toni made it to Taylor's fourth and final concert in Sydney on Monday, which would have seen her attend every single one of the star's shows in the city.

Many Swifties took to the comments section to share their jealously that Toni got to go more than once as they deemed her Taylor's 'number one fan'.

They wrote: 'You got to go two nights?'; 'You went again...I ❤ U'; 'Number one fan'; 'Just love this for you!!'; 'So lucky you are'; 'So jealous.'

Toni is not the first celebrity to have attended more than one of Taylor's shows Down Under, as G Flip went to two of the Eras tours shows at Melbourne Cricket Ground.

Taylor brought the Australian leg of her Eras tour to a close on Monday as she said farewell to her overwhelmed fans after seven epic concerts.
