Britney Spears lands her 10th Top 10 hit as "Till The World Ends" jumps from #20 to #9 in its second week on the Hot 100. Remarkably, Spears has amassed more Top 10 hits in the past four years than she did in the first eight years of her career (when she was at her peak) as a record-seller and pop-culture icon.
Meanwhile former Britney collaborator Lady Gaga continues to straddle the top of the Hot 100 charts for a fifth week running with her third album's lead single, the anthemic "Born This Way".
