The Grimes twins, who reached the live shows last year, met this year's acts at the results show and revealed that they had offered the remaining performers the wisdom of their experience from the competition.
"We were like Dr Phil advising them all on the show," Edward told DS. "We were running up and down the corridors, laughing and joking. We tried to lift their spirits."
However, John confessed that he had made an error when speaking to Cheryl Cole's act Waissel, claiming that he had accidentally called her "Weasel".
"A lot of the acts go back and think, 'Oh, I'm a superstar', but we were just really, really excited to go back", said John. "We got to meet all 1 Direction and told them what to do, offering them our advice and told them to focus. We hanged out with them for like 30 minutes.
"We also met Cher and Katie. I called her Katie Weasel, but then she told me her name is Waissel. But she was really nice and so was Cher."
The brothers also said that they thought Louis Walsh's Over 28s act Wagner Carrilho was "cool", joking that he looked like a character out of Disney's Pocahontas.
