Good luck, Mirando Cosgrove. You're probably gonna need it.

The young singer has a difficult task ahead of her next Tuesday on The Good Wife: she must follow in the impressive guest-starring footsteps of Michael J. Fox, who stood out on this week's installment of this CBS drama.

At least Cosgrove won't need to stretch very far. She'll play a celebrity that gets into a drunk driving accident, and then requires Alicia's help when faced with a murder charge. Get an early look at the episode titled "Bad Girls" via the following preview.
