Jedward are not allowed to cut their hair or change their quiffs while in the Celebrity Big Brother house.
The twins, John and Edward Grime, have had a clause written into their contract which states they are not allowed to take part in a task which forces them to cut or alter their famous hair.
X Factor judge Louis told BANG Showbiz that appearing in Celebrity Big Brother was a great move for the twins.
He said: "They're getting paid a lot of money for it and everyone loves them."
Celebrity Big Brother will begin tonight on Channel Five with a launch show – and an unexpected twist.
Host Brian Dowling said: "'It's something that will affect their time in the house. I can't reveal the surprise. Wait and see."
Aside from Jedward, other housemates expected to appear on the show include Kerry Katona, Sally Bercow – wife of the Speaker of the House of Commons, John Bercow and EastEnder Sid Owen.
