The girls, who finished the X Factor live tour in Cardiff on Friday, revealed how the N-Dubz star had been supporting them whilst on the road and as they record their debut album.
"She’s really great, we’re always on the phone to her," Perrie said.
Referring to Tulisa's recent sex tape scandal, Perrie went on: “Things have been difficult recently but she’s been such a trooper — she’s the most real person ever and I think her strength is why we won the show in the first place.
“We formed such a strong bond with her, she’s not a mentor any more, she’s a really good friend.”
Even Gary Barlow and Louis Walsh have been in touch with the girls, who became the first group ever to win the show in December.
Jade told The Sun: “It’s weird when you see them after the show because there isn’t that pressure any more. It’s like when you see a teacher after you’ve left school.”
But it was boss Simon Cowell who the girls dreaded meeting, and they were over the moon to find out that he was actually normal!
“Meeting Simon was like waiting outside the principal’s office. We felt like naughty schoolgirls and were all so scared that we could hardly breathe," Perrie told the newspaper today. “I don’t know why we thought Simon was going to be this monster. It was just amazing how normal he is.”
Little Mix are set to release their debut single next month.
