The veteran crooner sits on the panel of singing competition The X Factor Australia alongside British pop star James Blunt and Australians Dannii Minogue and Guy Sebastian.
However, Chris is struggling to pick songs for his contestants to perform because he knows so little about modern music, so he is being helped out by Fleetwood MAC star Stevie.
"Most of the music I know, I listen to music up to like 1968 and I don't know much about modern pop," he says. "So I'd call Stevie Nicks, she knows modern pop really good. She would call me back with lists of songs."
Chris even took the contestants he is mentoring to see his pal perform with Fleetwood MAC in Sydney over the weekend (24-25Oct15), and she dedicated the group's track Landslide to two of the aspiring singers on the show.
