Did Jack White take the opportunity of performing before a worldwide TV audience at the 2013 Grammys last night (Feb. 10) to swear? That's exactly what CBS is denying after swarm of viewers took to Twitter and other social media to claim White and singer Ruby Amanfu, a member of his all-female backing band the Peacocks, each sang the F-word instead of "fight" during the 'Love Interruption' line, "I want love to walk right up and bite me, grab a hold of me and fight me."

CBS executive Martin Franks told the Hollywood Reporter that multiple employees reviewed the performance and agreed it was clean.

"We had 10 editors, and three people on site, and all are experienced, all with multiple Grammy, multiple 'Big Brother,' multiple Tony experience, experience with doing these delays," he said. "They went through all of the rehearsals. They have prepared meticulously. And not a single one of them heard anything other than fight."
