|Dave J Hogan. Ed Sheeran performing at Radio One's Biggest Weekend|
It featured a wee break - for the star himself!
The Shape Of You singer was bursting so much that he had to stop his Saturday night concert because he "needed a pee" after performing his smash hit Galway Girl.
Then three songs later, Sheeran stopped in the middle of singing Photograph, saying "I'm so sorry Cardiff" before running off to the toilet again!
The 60,000 crowd cheered when he returned to the stage and Ed carried on singing where he left off!
He told the crowd "I've been gigging since I was 14 and I've never done that!"
Ed Sheeran is the first artist to play four nights at the Cardiff arena one after another.
Well Ed, you may be a record breaker, but when you've got to go, you've got to go!
