Janae Rosa impressed the judges and the nation at her X Factor audition which aired on seven on Wednesday night.

The crowd showed their love early erupting into applause before the 19-year-old Miss Rosa had barely sung two lines of Feeling Good by Michael Bublé.

An admittedly nervous Miss Rosa didn’t let her nerves get in the way of a stellar performance. 

“I am worried that when I go on the stage that I will have all of these thoughts going through my head or that it will go blank,” she said.

“This is by far the biggest opportunity of my life so I have to make sure to shake out the bad nerves and make my mum proud and just do my best.

And shake them off she did, with her performance delivering a roar of applause from the crowd – as well as three resounding yeses from judges Adam Lambert, Iggy Azalea and Guy Sebastian.

Miss Azalea, who had told Miss Rosa to take a deep breath and giver herself a couple of seconds to get prepared, said she had delivered a “special” performance.

“You rocked it, it was awesome,” she said before remarking that she loved how quietly confident Miss Rosa had been.

Her comments were echoed by fellow judge Guy Sebastian

“It is so true, you are so meek and mild and sweet and then there is this massive voice that comes out,” he said.

“I am definitely feeling good now.”

Continuing the positive feedback judge Adam Lambert said her vibe had been cool.

“That was unexpected and really funky,” he said.

Upon receiving her three ‘yeses’ and progressing onto the next round Miss Rosa ran straight into the arms of her clearly proud mother Anna, with whom she works at Target.

Miss Rosa told judges she had only been singing for five years.

“My singing teacher Lorraine [Sutton] holds these Easter Balls and such, she gives all these students a chance to perform on stage,” she said.

“We have people eating and they get entertained and all of the proceeds go back into the community.”
