2NE1's impact on K-pop is undeniable and far-reaching. Without a doubt much of K-pop's international recognition is all down to 2NE1 - without them, the genre wouldn't have nearly as many global fans as it does now.
The clip is strange to watch. Fans will scream on social media that Britney looks the hottest she has in years and proclaim that her famous armography is 'slaying,' and they'd be right. But then there's Britney, who looks eerily ageless, going through all the old motions like she never left 2004. It's the same thrusting, gyrating, and hairflips, the same genetically blessed male model love interest, the same robotic come hither stares to the camera.
