Christina Aguilera’s Pop Star Impersonations [Video]

Congratulations to Fultonville's Sawyer Fredericks. Last night, he won NBC's "The Voice." He wasn't the only one smiling however; Christian Aguilera had us grinning from ear to ear with her masterful pop star impersonations.

First up, it's the ever ageless Cher.

Heres she is with her Lady Gaga impression.

Her Salute to Miley Cyrus is stellar.

Here's Christina playing Sia.

She also did a Britney Spears impression. It contains a bad word so I didn't put it up here.
