The Mirror claims that the twins, who will join the X Factor tour when it starts on Monday, have asked for several different kinds of confectionery.
"Forget bottles of Jack Daniels and champers," a source said. "The twins are getting ten kilos of fizzy worms and cola bottles from woolworths.co.uk.
"They want foam bananas too, for the afterparty in their dressing rooms."
John & Edward have reportedly caused a row on the X Factor tour by being given twice as many songs as some of their fellow acts.
