Reese Witherspoon Sues Jewelry Company for Hijacking Her Face

Reese Witherspoon is a little preoccupied witherface -- because she just sued a jewelry company for using her mug in its ads.

Reese filed the lawsuit against Marketing Advantages International -- which runs the jewelry website Emitations.com -- claiming it exploited her name and face to sell jewelry and other stuff, including a knockoff of her engagement ring.

The deal breaker ... Reese insists she never gave the company permission to use her to hawk its wares.
