NBC has green-lighted "The Winner Is," a new vocal game show that showcases talented singers of all ages - soloists and groups that include adults, kids, teens, seniors, families and professionals - all of whom will compete in head-to-head singing duels-- Nick Lachey will host...

And speaking of Nick Lachey... he had an altercation with a San Diego fan who was wearing an Igor Olshansky #99 jersey (Igor played for SD from 2004 to 2008) at Qualcomm Stadium on Sunday during the Chargers and Bengals game; The Chargers fan says Lachey made one particularly offensive comment about Olshansky that crossed the line ... and that's when the fan's wife shot back to Nick, "Well, he lasted longer than your boy band."

ApparLachey flipped out and called the wife a host of profanities.
