If you've been on TikTok at least once over the past couple of months, you'll have heard of Kabin Crew.
Made up of a group of Irish kids, Kabin Crew came out of nowhere with one of the biggest tunes in the world.
'The Spark' quickly went viral on TikTok, with videos featuring the song being viewed over 350 million times online.
The group have since gone on to release a music video, do countless interviews and now, perform on stage with Becky Hill.
During her concert in Cork over the weekend, Becky Hill surprised the crowd of 15,000 by inviting Kabin Crew to the stage.
"Is it right that you've got a song to sing for everybody?" Becky joked before the kids ripped into 'The Spark'.
"They were INCREDIBLE!" One viewer wrote on TikTok. "Fair play to Becky Hill for sharing the stage, these kids will never forget it."
"Those kids must be so psyched, living their dream!."
Afterwards, Becky Hill spoke of how well the kids performed.
"They're so cute and they didn't get stage fright," she told Capital. "they smashed it, it was so nice."
