Ms. Spears has unveiled the full music video for her latest single "Til The World Ends", after giving fans a 30 second tease earlier this week. The video was like an "I'm A Slave (4 u)" part 2. It was awesome. I liked the underground partying. Effects was cool. The video had great artistic direction and I enjoyed it a lot, except for one obvious thing: Britney Spears looked like she was just learning how to dance. Throughout the entire music video my eyes were stolen by her dancers but not her. There was just no fire. No effort. I feel sad for her 'cause she's not the way she used to be. C'mon Britney what happened? Did your dance fever wore off? Anyways, check out the music video below and tell us what you think.
