Person 2: Hey did you just call me christina aguilera, because I'm not a stupid ugly fake plastic slut with no life and no talent at all.
Tried to out-sing Aretha Franklin on VH1's Diva's Live. Got her ass kicked.
At the 2002 Grammys, Patti Labelle sung her off the stage, as well as all the other "Lady Marmalade" girls (Pink, Mya, et al).
Has a reputation for being extremely rude and attempting to pick fights with other performers, notably Britney Spears (who used to be her friend), Pink (accused of stealing Aguilera's fashion choices), and Kelly Osbourne (whom she verbally abused at the 2003 MTV Europe Awards).
