Gangnam Style

South Korean rapper Psy has taken down Justin Bieber. The Biebs' 'Baby' had been the the most-watched YouTube video of all time, that is until a new champ was crowned.

Given that 'Gangnam Style' is one of the most popular songs of 2012, it's not surprising that Psy was tapped to close last night's American Music Awards. But it WAS totally surprising when MC Hammer joined him onstage for an awesome mashup featuring 'Too Legit to Quit.'

'Gangnam Style' star Psy has already won a 2012 American Music Award in advance of this weekend's ceremony, but more importantly, he got to perform two songs onstage with Madonna at her Madison Square Garden concert on Tuesday!

Don't worry, kids -- 'Gangnam Style,' the infectious viral hit by Korean rapper Psy, is bound to run out of steam sooner or later, right? Wrong. Last night on the MTV EMAs, host Heidi Klum starred in a brief clip with Psy and broke out her best horsey dance.

Thanks to K-Pop's Psy and his hit song 'Gangnam Style,' parodies of his video are popping up all over YouTube. From Mitt Romney to 'Star Wars,' there are videos for every fan base and situation. The latest of these parody videos, 'Mortal Kombat Vs Gangnam Style,' features cosplayers dressed as the 'Mortal Kombat' characters dancing in the Big Apple.

Yes, people are still making 'Gangnam Style' videos. In fact, if this one is any evidence, they're spending quite a bit of time on it too.

Oh, this is Gangnam style, for sure! Psy, the Scooter Braun-managed K-Pop sensation who has exploded into American consciousness on the back of his smash hit 'Gangnam Style' and the accompanying dance, covers the new issue of Billboard.

We know you’re probably sick of ‘Gangnam Style’ video parodies by now. Believe us, as much as we enjoy Korean rapper Psy, we’re getting a bit bored by all of his imitators. But how about a ‘Gangnam’ inspired mashup?

Remember last Halloween, the awesome 'Party Rock Anthem' house light show. Well, you just knew someone would put their spin on this year's smash, Psy's 'Gangnam Style.'

As hardcore 'Star Wars' fans, we've probably seen 'The Empire Strikes Back' 100 times. But this is the first time we've ever noticed a cameo by Korean 'Gangnam Style' rapper Psy. Were we sleeping during that part?

Everyone and their mother is crankin’ out ‘Gangnam Style’ parodies these days. No, seriously-- don’t you remember the mother-son pair who did an awesome rendition of PSY’s giddyup move? You’d think that after seeing versions from cats to Trekkies and everything in between we’d be a little sick of this craze, right?

Remember that rapping weatherman who made storm patterns seem fun? Well, meteorologist Nick Kosir is back with a bang, and this time, he’s going at it PSY-style.

Since Halloween is only a little more than two weeks away, it's high time we all immersed ourselves in something scary and spooky. To that end, we present a truly frightening mashup of the 'Ghostbusters' theme with Psy's monster hit 'Gangnam Style.' You might not think they'd go well together, but somehow they do.

Finally! At long last parents have a way to muzzle their children and get them eating without the kids acting like ungrateful sacks of complaint. Psy does it again! Give 'em 'Gangnam Style!'

One of our new favorite things about Halloween is funny, candid pictures of people being scared senseless in a haunted house. We had to ask ourselves though, what were they seeing that was so scary? We put our heads together, and we think we've figured it out. Here are our guesses at what was so scary in that haunted house. Because it certainly wasn't a guy in a wolf mask jumping out of nowhere.

An exchange student from South Korea at Northwest Carrabus High School in Concord, North Carolina performed the dance from PSY's international K-Pop smash hit 'Gangnam Style' at a pep rally. We wouldn't be surprised if he is now the most popular kid in school.
