Britney moved 276,000 copies of her new album to bury her valiant second-place competitor, Wiz Khalifa, who sold 197,000 copies of Rolling Papers. While the numbers are impressive, they aren't particularly special for Britney, whose 2008 album Circus sold 508,000 copies in its first week.
The news comes this week along with the debut of Britney's second video from the new album. "Till the World Ends" debuted on Vevo.com on Wednesday and has already racked up more than a million views. Check out the post-apocalyptic spectacle of a video below.
