MARK RONSON has to keep an eye out for Curly Wurly bars being hurled at the stage when he is performing — they can be painful if they hit him.

The craze started after the DJ and record producer revealed he was a big fan of the Cadbury chocolate treat when he lived in the UK as a child.

‘Because I grew up in England and moved to the States, people used to ask me, “What’s the thing you miss about England?”’ Ronson told Channel 4’s Sunday Brunch.

‘I’d say, “Well, I loved Curly Wurlys”. And I think some more passionate fans started throwing them.

‘You know, you throw a Curly Wurly at a festival, it picks up some speed and you get hit in the head. It’s like it might be a gesture of love, but it can be painful!’

Sunday Brunch presenters Simon Rimmer and Tim Lovejoy then offered the 43-year-old a chocolate cake with a Curly Wurly-inspired design on the top.

‘That would hurt if someone threw that at you on stage, for sure,’ joked Mark.

The star, who earlier this year won an Oscar for co-writing Shallow for A Star Is Born, has just released a new album, called Late Night Feelings.
