The End of 'Gangnam Style'? Even Psy apparently is a little over "gangnam style." The Korean rapper is reportedly ready to move on and prove he isn't a one-hit wonder. The rapper, who turned 35 on New Year's Eve, told MTV News his performance of "Gangnam Style" on "Dick Clark's New Year's Rockin' Eve" could be his last. "The song became too popular, and so you start to have some concern about its life period," he said. "I'm really working hard on a new single right now, and I'm not saying ['Gangnam'] is ending on 'Dick Clark' - I still have a lot of invitations to perform it … I'll be in Paris, and in February I got invited to perform in China, and I've still got to do promo. So let me say that in America I need a new single because 'Gangnam Style' got too popular, so I've got to write a new single."

New Year Means New Laws As people rang in 2013, new laws took effect across the country. Sorry Kansas cat lovers but Wellington, Kan., now restricts the number of cats in a household to no more than four. Daredevils in Illinois be warned, a new state law imposes a fine of $1,000 on anyone who pops a wheelie on a motorcycle while speeding. But motorcyclists in Illinois will now have a free pass to run a red light. In Florida, it is no longer illegal to flash your headlights to warn drivers about a speeding trap set by police. Kentucky has outlawed releasing pigs into the wild and anyone caught doing it will be slapped with a fine. Concord, Mass., is now the first town in the nation to outlaw plastic bottles. More than 800 laws will take effect in California including one that allows computer-driven cars on the roads, but a person needs to be in the passenger seat at all times. In North Carolina, it's a misdemeanor to steal used cooking oil but it's a felony if the value of the stolen grease - or the grease plus its container - is worth more than $1,000.
