Politically incorrect? Often. Fabulously funny? Always.

Joan Rivers just turned 80, but she hasn't softened or slowed any.

The comedienne enjoyed a big uptick in her popularity starting in 2010, thanks first to the documentary film about her, "A Piece of Work," and then to her gig hosting the zeitgeisty "Fashion Police" on E! "Fashion Police" is, I'd argue, the funniest thing on TV.

What you'll see when Rivers does stand-up Saturday at MGM Grand at Foxwoods will be very much the same Rivers you see on "Fashion Police" - ribald, racy, outrageous, and flat-out hilarious.

As she recently told the Hollywood Reporter, "I got a lot of flack for a joke I made about Heidi Klum and the Nazis ("The last time a German looked this hot was when they were pushing Jews into the ovens"), but I never apologized for it. I said Justin Bieber looked like a little lesbian - and I stand by it: He's the daughter Cher wishes she'd had."

The bottom line for Rivers: "I've learned to have absolutely no regrets about any jokes I've ever done."
