South Korean rapper Psy is going nuts

Not content with starring in the most-watched video in YouTube history, the man behind viral hit "Gangnam Style" is to appear in a Super Bowl commercial for... pistachios.

"The Wonderful Pistachios brand is fun, just like me," Psy said Wednesday by way of a press release from Paramount Farms, which owns the upmarket California snack label.

"Also, I love pistachios and I look good in green."

It will be Wonderful Pistachios' first spot ever during the Super Bowl, the annual American football classic, set for February 3 this year, that is also the most coveted showcase for commercials on US television.

Psy made Internet history shortly before Christmas when "Gangnam Style" -- featuring his signature horse-riding dance -- clocked more than one billion views on YouTube.

CBS television has been selling Super Bowl advertising at record prices this year, with 30 seconds going for more than $4 million dollars, USA Today reported Wednesday, quoting network executives.

Last month, Wonderful Pistachios featured Filipino boxer Manny Pacquiao in its ongoing "Get Crackin'" series of commercials and sponsored his Las Vegas bout with Mexico's Juan Manuel Marquez.
