Foxy Holly Willoughby was also a hit, netting spin-off Xtra Factor a best ever 1.5MILLION audience.
More than half of all TV viewers tuned in to Girls Aloud star Cheryl’s debut as a judge — 1.5million more than in 2007. Simon Cowell said: “We’re back bigger and better than before. It really is the best series we’ve done.”
Simon, 48 — also overjoyed at the draw of ITV2’s Xtra Factor host Holly, 27 — added: “Getting Cheryl on board was brilliant.
“I’m pleased she’s done this. She really is one of the best I’ve worked with. She’s not afraid to speak her mind and most of all she gets it.”

HOST Dermot O’Leary has been so busy with the show he’s missed Big Brother for the first time.
