John and Edward are being given more performance time than other acts on the ‘X Factor’ tour.
The ‘Under Pressure’ singers – who now go by the name Jedward – perform four songs on the show, the same amount as winner Joe McElderry.
John, 18, said: “It's because of this year's show and all the stuff there was about us. We are not going to complain - it's what we are being told to do.”
However, fellow participants - who finished higher than fifth placed Jedward - are said to be unhappy.
A source said: “Some of the others who got further in the competition might not be too happy, but Jedward are the stars.”
Jedward and Joe are the only two acts to have been signed up to a record label following their performances on ‘The X Factor’.
The twins are expected to debut at number one in the UK charts on Sunday with their single ‘Under Pressure’ – a duet with rapper Vanilla Ice.
Other ‘X Factor’ acts Olly Murs, Stacey Solomon and Danyl Johnson have signed up with holiday camp company Butlins to perform over the summer.
