Fashion Police Show: Sarah Jessica Parker's Perp Walk

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

Sarah Jessica Parker may fit in at a British royal wedding but don't count Joan Rivers as a fan of this oversized, abstract fascinator.

"I hope Sarah only wore this hat once and then immediately donated it to the National Dumb-Ass Museum in Washington, D.C.," joked the Fashion Police host.

And that's not all. The hostess with the mostest talks sympathy sex, attention-seeking stars, 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.
