Tilt Ya Head Back

Regarding Christina & Nelly's performance at the VMAs:

MSNBC:Best performance: Christina Aguilera and Nelly prove to all the lip-synchers out there, cough Britney cough, that it is actually possible to sing and dance at the same time.Brian Hiatt,

Entertainment Weekly:Best Makeover: The newly curly-headed and blond Christina Aguilera looked and sounded rejuvenated during a performance of "Tilt Ya Head Back," her "Superfly"-sampling new single with Nelly. Dancing and belting out bluesy riffs with equal proficiency, Aguilera seemed like a rising star again -- not an aging teen-pop act fighting for relevance. Plus, in her flapper outfit, she was sexy but not particularly dirrty.

Roger Friedman, FOX News:The VMAs are a sad story, with much cacophony, preening and lip-synching, and not much music to go around. With the exceptions of Alicia Keys (and guest Stevie Wonder), OutKast and Christina Aguilera, we have on our hands a generation of illiterates and unwatchables.

Liz Smith, Newsday:I did think the performances of Usher, Christina Aguilera (with Nelly), Alicia Keys, Stevie Wonder and Lenny Kravitz were pretty sensational. In fact, Christina, who was part rocking, sexy, soul sister and part '20s flapper, looks like she is ready for a big-time Hollywood musical. What a voice on that girl!
