Cher Lloyd says she would give Simon Cowell "a run for his money" if she returned to The X Factor as a judge.
The former contestant said she was missing her family and British culture since moving to America after finishing fourth on the ITV show in 2010.
Simon is the only judge confirmed to appear on the next series of The X Factor after Rita Ora, Cheryl Fernandez-Versini and Nick Grimshaw announced they would not be returning.
Speaking at the BMI Pop Awards in Los Angeles, Cher, 22, said she was unsure if she would be able to return to the show because she was about to release new music.
She told the Press Association: "I've got a lot going on here at the moment. It's been a while since all of that.
"I think I'd probably give Simon a run for his money.
"I miss my family. I miss the culture really. It's a different culture here. I'm still getting used to it."
Cher, from Malvern in Worcestershire, said she was no longer in contact with Cheryl, who was her mentor on The X Factor.
She added: "I think with me being here and just being so focused on my music, I don't really get to go back a lot. I'm hoping to get back to release music soon."
Rita announced on Monday that she had quit The X Factor after appearing for just one season, while Cheryl said she was leaving to focus on her music career.
Radio 1 DJ Nick has also quit as a judge, while the show's presenters, Caroline Flack and Olly Murs, confirmed they would not return.
Former judges Nicole Scherzinger, Louis Walsh and Sharon Osbourne have all been linked with a possible return, while presenter Dermot O'Leary confirmed in March that he was coming back to the show.
Cher, who got married in 2013, scored a UK number one single with her debut track Swagger Jagger in 2011. The singer has toured with US superstars Taylor Swift and Demi Lovato.
