How Christina Aguilera uses that range
She ornaments almost everything: long melismatic chains, turns and slides on nearly every held syllable, all sitting on a thick, forward belt that keeps chest weight up near G5. Vibrato is fast and wide, usually started immediately rather than saved for the end. Above the belt she flips to whistle, which is a separate mechanism and not an extension of chest. Ornaments added before the support exists go sharp, and the throat grips to hold them.
What is Christina Aguilera’s vocal range?

Heavy melisma over a thick, forward belt; adds whistle notes well above the staff when she wants them. That cited span is wider than 96% of the 357 voices in this library.
