Simon Cowell is currently working to replace axed judges Paula Abdul and Nicole Scherzinger, who will not return for the second series of the Fox competition later this year.
However, with two famous faces poised to join Cowell and LA Reid, the 'Collide' singer added: "For new judges, I'd like to see someone like Pink. She would be a really cool addition, a strong female with a different perspective and a different angle."
Discussing her upcoming third album, Lewis - pictured with Pink at the 2008 American Music Awards - told the magazine that she is currently in the final stages of the project.
"I'm in the process of arranging it and putting the finishing touches on stuff. I'm really just enjoying the final moments," she said. "I would love to go on tour with this album. That's my favourite part - performing live."
Recent reports have suggested that Britney Spears could appear as a judge, while both Rihanna and Fergie have denied involvement.
