Bynes attacks model in Twitter rant

Amanda Bynes has branded model Chrissy Teigen "ugly" in a Twitter tirade.

The troubled actress launched a venomous attack against the Sports Illustrated model and claimed she is "far prettier" than Chrissy in her tweets after Chrissy questioned her mental state in light of her recent woes, including an arrest for marijuana possession in New York City last week, which resulted in Amanda making an unproven accusation that a police officer touched her inappropriately.
