Courtney is being sued for defamation by a fashion designer named Dawn Simorangkir. 

Dawn says that in a series of Twitter rants in March of 2009, Courtney portrayed her as “a drug-pushing prostitute with a history of assault and battery who lost custody of her own child and capitalized on Love’s fame before stealing from her.”

Here’s how Courtney is defending herself:  Her attorneys are going to argue that Twitter is so addictive and immediate, that Courtney didn’t realize she was doing anything wrong, or how her words would be interpreted.

This will be an interesting case to watch, because it might shape how the law handles Twitter in the future and whether someone’s Tweets can be considered libelous or defamatory.
