But can she follow in their footsteps and make it all the way through to the live shows?
Just like the 4th Impact (originally 4th Power) sisters, 33-year-old Ivy Grace has flown from the Philippines to audition for The X Factor.
She tells cameras in tonight's show: "Last year I was browsing the internet because I only watch X Factor on YouTube because I don't have television. I watched 4th Impact, a group of four Filipino sisters. When I watched them I got really inspired that if they can make it, I can make it two."
Ivy Grace, who has a little girl back in the Philippines, continues: "I'm not getting any younger, but I can still be on stage which is why I am here on The X Factor. If I get the four yesses today, I go crazy, I want this."
After a VERY big and powerful performance of Whitney Houston's All The Man That I Need, Simon Cowell reacts: "What just happened there?!"
"She just sang our faces off, pretty much, that's what happened," replies Nicole Scherzinger.
Asked why she chose to come over just for The X Factor, a tearful Ivy Grace says: "For me, I believe this is the biggest competition and I want to be a part of it. X Factor can give me the stepping stones I need to do good in the future because this is all for my daughter."
Will Ivy Grace follow 4th Impact and get through to bootcamp?
Watch her audition and find out when The X Factor 2016 auditions continue Sunday night at 8PM on ITV.
