Mariah Carey looked better than ever as a judge on this season's 'American Idol' finale and we were pretty excited when she took to stage to perform a medley of her hits.

Everything seemed right: her sequin, mermaid-esque ball gown hugged her well-maintained curves and the stage wind blew her hair back as if she were an angel descending from heaven. But as soon as the track started, things seemed a little strange.

The camera constantly pulled far away and only did a few close-ups of the performance, as if trying to distract us from Mariah's singing. She performed 'Vision of Love,' 'Make It Happen,' 'Hero,' 'My All' and 'We Belong Together' before ending with her latest, '#Beautiful.'

Watch the video yourself and tell us if you think she was lip-syncing.
