Melissa Armstrong, 21, appeared in front of the new judging lineup of Gary Barlow, Tulisa Contostavlos, Louis Walsh and Nicole Scherzinger to perform a cover of Cole's 'Promise This'.
"You have a nice, sweet voice," Contostavlos told her at the audition in Newcastle yesterday (June 18).
However, Scherzinger advised her that she should follow her aunt's career by joining a girl group.
She said: "I could see you doing country music or being in a girlband."
Nicole Scherzinger was confirmed as the show's permanent fourth judge last week.
Cheryl Cole's scored the fastest-selling number one single of 2012 so far with 'Call My Name' on Sunday.
