Jennifer Love Hewitt joining the X Factor USA is "pure speculation", sources have revealed.
The Ghost Whisperer star had been rumoured to be in the running to be a judge for the show's third series alongside Simon Cowell and Demi Lovato, with a source telling US Weekly: "Simon is very interested."
But a representative for The X Factor said: "This is pure speculation."
Kelly Rowland, who was previously a judge on the UK's X Factor, is also said to be in the frame along with country singer Reba McEntire, following the departures of Britney Spears and LA Reid.
Mario Lopez will return to host for a second year, but without co-presenter Khloe Kardashian.
X Factor boss Simon Cowell has said: "I'm thrilled Mario is back for Season Three of The X Factor.
"Hosting a live show and keeping the judges - especially Demi - in line, is not an easy job, but Mario is a pro and we are glad he's coming back."
