WATCH: Did Mariah Carey Lip Sync on 'American Idol' Finale?

Did you catch Mariah Carey on American Idol last night? The diva performed a medley of some of her greatest hits during the show’s finale, causing what felt like everyone on social media questioning whether it was really a “live performance.”

The 43-year-old performed snippets of “Vision of Love,” “Make It Happen,” “My All,” and “Hero” – and the overall performance felt just… a bit choppy, uncoordinated.

And while her voice may have been a bit off, Carey didn’t fail with her signature exaggerated hand flailing and flicking of the wrist during the performance.

Missed the performance? Want to be the judge yourself. The main snippet that was a red flag for us goes down at around 2:59.

Watch the video after the jump and then tell us – do you think Carey was lip-syncing?
