Nicole Polizzi

It's been all business for the stars of MTV's "Jersey Shore," with the cast kicking off its fifth season of the show last week and a few select stars continuing on their path of brand domination.

At the Consumer Electronics Show (aka #CES2012) in Las Vegas this week, industry execs find themselves competing for the spotlight with celebrities pitching their new tech gadgets. Among the stars promoting products, both Nicole "Snooki" Polizzi and Paul "DJ Pauly D" DelVecchio announced they are partnering with audio companies to design their own headphones.
