Tulisa Contostavlos's girlband - Jesy Nelson, Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall - are the most successful all-female group in X Factor history and are now bookmakers' favourites to win the ITV1 talent show.
Talking about their popularity, the girls argued that their "natural" and "normal" image was behind their breakout success.
"What's good about us is that we're normal girls and we look up to the other girlbands ourselves," Edwards told Digital Spy.
"We're using our own experiences of loving girl groups to build something that other girls can relate to. We've been there like other girls and thought, 'Why don't I look like that? Why can't I be more like that?'
"We're real normal girls living the dream. You don't have to be fake. It's just us being natural on stage and having fun."

Nelson commented: "I think boys get it a little easier on the show because I think when girls see nice-looking boys, they go, 'Aww', and get lots of votes just because of that.
"Whereas girls can be intimidated by other girls. I think that's why previous girlbands [have failed] in the past."
Pinnock insisted that the stars would never be influenced by criticism of how they look or dress.
"I remember there was a comment about what we were wearing and it said that we looked like we'd been dragged through a hedge backwards," she said.
"But you know what, we are who we are and we won't change for anyone. That's the message we want to put out."
Edwards added: "We've got to stand up for women. All girls across the nation need someone to look up to. Dress how you want. Don't listen to anyone if they say they don't like your outfit. You have to be strong. It's hard being young girls in this competition."
The X Factor semi-final airs on Saturday (December 3) and will feature Little Mix, Marcus Collins, Misha Bryan and Amelia Lily fighting for a spot at the Wembley Arena finale.
Little Mix said that despite support from bookies, they were not feeling confident about reaching the final.
"People maybe won't vote thinking that you're safe, but that's not the case at all," said the group. "Anyone has got a chance of winning now."
