Chuck Klosterman has the definitive line on Britney Spears: “Either Britney Spears is the least self-aware person I’ve ever met, or she’s way, way savvier than any of us realize.” Based on Spears’ latest hit single (and future lap dance classic) “Gimme More,” I lean toward the former—only a person completely lacking in self-awareness could marry Kevin Federline, spend a year eating Funions and Cheetos in front of paparazzi, teach her toddler how to drive stick-shift, divorce Kevin Federline, go crazy, shave her head, go to rehab, leave rehab, go back to rehab, and then record a song that sounds exactly like what she did back before any of that stuff happened. In this case, Britney’s lack of interest in introspection is a plus—welcome back, you crazy lil’ Mouseketeer!
