Fashion Police Show: Jessica Alba's Perp Walk

Hostess with the mostest Joan Rivers lets the actress know what she really thinks of her.

What do private parts, lesbian aunts and peeing in public have in common?

Last week's Clinton Foundation fundraiser brought out a bunch of stars and the best of Joan Rivers' jabs.

"I personally liked this outfit better on Nanny McPhee," the Fashion Police host quipped of Jessica Alba–and that's one of the nicest comment we could include here. 

But that's not all. The hostess with the mostest also covers desperate dressing, camel toes and more!

So click in and get all of Joan's jokes that didn't make it on air in our sassy sartorial photo gallery.
