John and Edward Grimes shot to fame with their dance routines and trademark quiffs on the X-Factor.
They also represented Ireland this year in the Eurovision Song Contest.
Other stars expected to appear on Channel 5's Celebrity Big Brother include Sid Owen, who is a former EastEnders star and Kerry Katona.
Meanwhile, Olly Murs, the X-Factor's 2009 runner-up, has challenged Big Brother producers to split up Jeward if they enter the house.
"It would be interesting. I've known the boys for two years and I've never seen them apart so it would be interesting to see what would happen," he said.
