US Chart Roundup: Christina Aguilera's "Your Body" Belly-Flops

PSY's "Gangnam Style" may have conquered the UK chart this week, but it's unable to unseat Maroon 5's "One More Night" on the Billboard Hot 100. And even though the South Korean stud promised to perform the song shirtless if he got to #1 here, he's doing it today anyway via some Ustream trash concert. Get ready for sexy.

Three broads crash the Top 20 this week with new songs: Taylor Swift debuts at #7 with her latest Red offering "Begin Again"; Ke$ha's "Die Young" enters at #13; and Rihanna's new single "Diamonds," from her upcoming 74th studio album, arrives at #16.

Meanwhile, you would have thought that the premiere of Christina Aguilera's "Your Body" video would have helped the single, but it's now dropped from last week's debut position of #34 to #64. Maybe she didn't wear enough rainbow-colored extensions in the slutty trailer park?
