Gary Barlowand Nicole Scherzinger, labelling them "rude".
And twosome Charlotte Rundle and Simeon Dixon have also branded rival Christopher Moloney a "diva" and claimed their fans were unable to get through on the voting line.
Charlie told The Sun that she was put off by the sight of Gary and Nicole having a chat as she [uuid=8a7ac1aa-d235-48c1-ac1d-92ae0eb76888]performed in the sing-off[/uuid].
"They were whispering to each other and I thought, 'I'm trying to sing for my place and they were chatting'. That's just rude."
While Simeon said he thought there had been a problem with their phone line.
"MK1's vote line went down. A lot of our fans were tweeting saying they couldn't vote for us because there was something wrong with our line."
But a show spokesperson denied there was a fault, saying; "The phone lines have been checked and there were no issues."
The duo also had some harsh words for their rival Christopher Moloney, who has been accused of high-handed behaviour in recent weeks.
Simeon said: "Chris surviving was a bit of a shocker. He got really lucky. He is the biggest diva."
And Charlie adding: "If there's not a drink around or he doesn't get his food on time or go home in the right taxi, then it's a bit of a nightmare. The simple things that shouldn't matter, matter to him."
But it's not all been doom and gloom since their exit from the show, they've found time to have a joke about their job prospects.
Talking to Digital Spy about Rylan Clark's future, Charlotte said: "Rylan will definitely be successful whether it's in TV or as a dancer, or even have his own show.
"I definitely would watch it. I've already designated my own section on it. I'd do the weather or the news or something."
