Viral Olympian Raygun joined Tones and I onstage

Olympian breaker Rachael ‘Raygun’ Gunn has surprised those at Tones and I, taking to the stage at the Australian singer's Melbourne show.

In a video posted to her Instagram Tones and I said "Raygun the most beautiful kindest full of life human I have met. It was an honour to celebrate you last night."

It comes less than a week after 'Raygun' announced he would no longer compete in public events.

Posting on Instagram the morning after the performance, Raygun said it was a thrill to be up there.

“What an amazing experience! Thank you Tones and I for inviting onto your stage. So much love,” she wrote.
