WORST IDEA 9/14/10: Jennifer Lopez joins American Idol as judge

She can't sing or write songs and she's famously a "diva," (which is a nice way of saying jerk), but somehow Jennifer Lopez has landed a $12 million, three-year deal to serve as a judge on American Idol. Of course, nothing in Lopez' past suggests that she has any ability to offer entertaining opinions and certainly nothing she has ever done shows she will be good at handing out criticism. If FOX wanted famous, well, they got it, but Lopez won't offer anything to the program and the void left by Simon Cowell's departure remains huge.
