HOLY LIPSYNCHING!

Mariah was soooooo faking singing “Bye Bye” on American Idol last night.

Watch it & let me know what you think…

HERE is a really dumb video of PETE WENTZ and ASHLEE SIMPSON pretending that Ashlee is preggers.

Oh…and the video was made in FEBRUARY…before they got engaged and rumors started up that she was knocked up for reals.

Geniuses.
