A young girl who won a local public speaking competition with a speech on how much she loves Taylor Swift had her wildest dreams come true on Sunday night when the megastar gave her her hat onstage at her concert in Sydney.

During each of her shows, Taylor, 34, gives a signed hat to one lucky fan in the crowd while singing her hit song 22.

On Sunday evening, Swift plucked five-year-old Lily from the crowd so she could gift her the signed black bowler.

The youngster was overwhelmed with emotion as she approached the edge of the stage before Swift kneeled down and put the hat on her head.

Fans of Swift were quick to gush over the adorable footage which went viral on social media.

‘Literally the cutest ever,’ one person wrote, as a second added: ‘I was rooting for her to get it.’

The moment was made even more special as her mother had to wait in line ten hours to get tickets to the show.

During Taylor’s first Sydney show on Friday, Swift chose young Scarlett, who is fighting an aggressive form of brain cancer, to be the recipient of her hat.

Earlier, Scarlett’s stepmother Natalie had posted to social media that her step-daughter’s wish had been to meet Taylor.

‘Scarlett was granted a “Wish” from the Make A Wish Foundation and her wish was to meet Taylor Swift,’ Natalie wrote in the post.

‘Unfortunately, they told us this wasn’t possible so through the power of social media and some generous people we made attending the concert happen and got tickets.’

She then shared a picture of Scarlett, who has been given just 12-18 months to live, holding a poster that read ‘Taylor can I have the 22 hat please?’

Later at the concert, the young girl’s wish was Taylor’s command as she invited Scarlett up to the stage, embraced her while she handed over the fedora, then tenderly kissed her hands.

After performing three sold out shows over the weekend, Swift is set to that the stage in Sydney for the final time on Monday evening.
