 The halftime show featured Kelly Clarkson, who performed "Since U Been Gone", and Ashlee Simpson, who performed "La La".Simpson's performance—coming on the heels of a lip-syncing incident that occurred during on "Saturday Night Live" the previous October—was poorly-received, with Simpson receiving a shower of jeers from the crowd at its conclusion.ESPN writer D'Arcy Maine described Simpson as "torturing those in the crowd with each attempt at a note, sounding more and more like a shrieking hyena as she went on", and considered it justification for "why she preferred to lip-sync".
