The Voice Kids coaches arrived to work by tram at the start of tonight's show - but they appeared to break some rules.
Jessie J, Danny Jones, Pixie Lott and Will.i.am caused chaos as they hopped on the Manchester Metrolink during rush hour.
The commuters were shocked to see the four famous singers on their way to MediaCityUk in Salford, with one woman saying: "Fancy seeing you on the train."
Will replied: "You know we do this every morning. Usually at 9am."
McFly singer Danny then gave them a song on his guitar and started playing Back Eyed Peas hit 'I Gotta Feeling'.
Will was really feeling in the mood and started banging his fists on the windows.
The rapper then climbed up to the ceiling and started thrusting his crotch while placing his feet on the walls.
Everyone started singing along and began clapping when they finally reached their destination.
Danny said: "That's how we get to work every morning. Not too late are we?"
The coaches then walked arm in arm into the studio before settling down for the first audition of the day.
The rules state that no one is allowed to perform with or without an instrument on the tram, but the judges probably got permission before they got on board.
The Voice Kids viewers took to Twitter after watching the coaches get to work on the tram.
One viewer asked: "Why wasn’t I on that musical tram with Jessie"
"Would not cope with those 4 coaches getting on my tram very well tbh," added another.
A third said: "What I would have given to be on that tram with them"
