The 27-year-old singer starred on the ITV show back in 2011, when she joined Little Mix, and Jade has insisted she can still empathise with the contestants on 'Little Mix The Search'.

Jade - who appears alongside her bandmates on the BBC series - shared: "Before I got put in Little Mix, I auditioned three times.

"I remember when I auditioned my legs were like jelly, I was shaking so much. I was never, ever going to give up on my dream. I would have been turning up till I was an old woman, till I made it."

Jesy Nelson, Jade's bandmate, can also still remember her own experience of auditioning on 'The X Factor'.

After watching one of the acts perform on 'Little Mix The Search', Jesy said: "Watching this audition takes me back to what I felt on my first audition.

"The most petrified I’ve ever been in my whole entire life and you can’t control it.

"It doesn’t matter how many deep breaths you take, how much you try and mentally prepare yourself, nothing prepares you for that moment."

Similarly, Perrie Edwards knows that auditions can be life-shaping moments.

The blonde beauty auditioned for the group nine years ago and they've subsequently established themselves as one of the biggest bands in the world.

She said: "My very first ever audition was to be in this band.

"Oh, the nerves. All those feelings come flooding back when I see somebody just so passionate about something. It’s their chance to change their lives."
