That said, Leighton warbles on Cobra Starship's pop hit "Good Girls Go Bad," which this week enters the Top 10 of Billboard's Hot 100 Singles at #10. Might this be a precursor to Leighton's supposed singing career? Maybe it's a good sign that she'll succeed, where so many other of TV's aspiring ho's (Heidi Montag, Hayden Panettiere, Joey Lawrence, etc.) have flizz-opped!

Another jam that dropped then flew back up is Shakira's "She Wolf," which scurries like a rabid Twilight tween at the sight of Taylor Lautner up from #41 to #21.
Meanwhile, poor Ting Tings. They had one brief week in the Top 40 when they inched up to #39 on the previous chart, and have now dropped to #41. What were those immortal words Ace Of Base taught us, kids? That's right—life is demanding without understanding.

Goodbye to you, goodbye to everything that I knew...
