Psy

President Obama watched Psy perform at the 'Christmas in Washington' charity concert on Sunday night and shook hands with the South Korean pop star, despite the controversy surrounding his 2004 performance of a song that called for killing “Yankees” in Iraq.

This could be trouble. Just one day before he's scheduled to perform 'Gangnam Style' for President Obama at the Christmas in Washington DC 2012 concert, Korean rapper Psy is in hot water after an unconfirmed report surfaced suggesting that in 2004 he performed at an anti-American concert in Seoul, South Korea and rapped lyrics about "killing those f---ing Yankees."

The laws of pop physics state that what goes up must come down -- which means that Psy can expect one heck of a comedown after the massive success of the worldwide novelty hit 'Gangnam Style.' But that doesn't mean he's just sitting around waiting for everyone to get sick of his song.

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.'

The fact that K-Pop sensation Psy, who shot to fame as a YouTube sensation, closed the 40th anniversary edition of the American Music Awards tonight (Nov. 18) with his viral smash 'Gangnam Style' was indicative of the times we live in. The AMAs may be four decades old, but they change with the times and are certainly embracing the digital age.

'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!

Psy brought his global hit 'Gangnam Style' to the Frankfurt, Germany stage of the 2012 MTV EMAs last night (Nov. 11).

So we lost count as to how many outfit changes Heidi Klum has had during the 2012 Europe Music Awards, but our ears perked up and paid attention when she announced that David Hasselhoff (yes, the David Hasselhoff) would be handing out the award for Best Video.

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?

- Awkward! Despite breaking up with Conor, Taylor Swift still plans on buying a mansion near the Kennedys in Hyannis Port, Mass.

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?

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.
