gangnam flash mob'South Korean pop-star Psy can't stop, won't stop. The 34-year-old dancer, singer, rapper, did I mention dancer?, was on hand at the Grove in L.A. yesterday paying a visit to masterminds Maria Menounos and Mario Lopez on the set of Extra when he got a little surprise. While teaching Maria/o to do the Gangnam Style, he was suddenly whisked away into the crowd where, unbeknownst to Psy, a bunch of people were waiting to show of their dance moves, as well. It was a flash mob, and Psy was totally swept up in a sea of strangers doing their best horse-riding impressions. Watch:

The fact that so many people were a part of this flash mob shows just how popular Psy is becoming. He's gaining fans by the minute because, come on, who doesn't love a pudgy guy in a blue sweater vest rapping in Korean?

Psy is the antithesis of what we've been programmed to idolize in our celebrities -- he's not especially good looking, nor buff, nor stylish -- but his charm, charisma, and fun-loving attitude have drawn us in. Psy's like the new Snooki, only with talent. Both represent the complete opposite of an Angelina Jolie or a Kate Middleton or a George Clooney, yet we can't seem to turn them away. Psy's got staying power.

Can't wait to see what he does next.
