The former Pussycat Doll joined the judging panel for the current ITV series, but has said that she hasn't decided whether or not to return in 2013.
"I'm really glad I did the show," Scherzinger is quoted as saying in The Sun. "I don't know if I'll come back next year. End on a high, right?"
Scherzinger hinted that she would like to focus more on her music career next year, saying: "This year has changed my life. As an artist, it's put into perspective what I want, how to go about it.
"People have made me so comfortable, and I have to thank you."
The singer's acts Jahmene Douglas and James Arthur will compete against Christopher Maloney for the 2012 X Factor crown this weekend.
Scherzinger will perform with both of her acts during the live show.
The former X Factor USA judge is currently easily topping Digital Spy's poll to find readers' favourite panellist.
