Pink surprised an inspiring cancer survivor in Melbourne - and it gave us all the feels!

One lucky 16-year-old has just had his dreams come true; as he got to meet the one and only Pink!

Calvin, a survivor of brain cancer who lives with Down Syndrome and Autism, caught the 'Beautiful Trauma' singer's attention after his mum shared his story on social media back in 2013.

"My special little guy Calvin is ready to go to his 1st ever Pink concert. Just after we bought our tickets through presale he was diagnosed with a life-threatening brain tumour. He already has Down Syndrome so it was all confusing for him," his mother, Nerida, wrote ahead of Pink's The Truth About Love World Tour.

"The Pink tickets quickly became a beacon of hope, a goal, a light at the end of a really dark tunnel. We listened to Pink and talked about the concert for every treatment he went through. With strength, courage, positivity and endless happiness he pushed through."

"Thanks Pink, for showing him strength and positivity," she added, as he nearly missed attending the concert.

The tweet ultimately went viral and the superstar herself saw the message, which brought her to tears.

Fast forward five years; the 38-year-old singer found Calvin and invited him backstage for a private meet and greet before her show at Rod Laver Arena in Melbourne on Tuesday.

Joined by his mum and grandmother, Pink described the moment as "one of the sweetest memories" of her life.

Awwwwwwwwwwwww!
