Kathy Griffin has had a rough week: on the weekend she lost her beloved older sister after a long battle with cancer.

It was yet another challenge in what’s already been a tumultuous year for the 52-year-old American comedian, who’s coming to Australia next month as part of her first-ever world stand-up tour.

In May, Griffin stopped the global media in its tracks when she posed for photos holding a fake version of Donald Trump’s severed, bloodied head, prompting severe backlash.

Griffin lost friends, received death threats and became the target of a two-month long US federal investigation.

“I was on the f–king no-fly list,” Griffin tells The New Daily, “It was a big deal.

“Trump fans tracked down my sister with cancer, they were leaving hate messages on her phone while she was dying. They even found my 97-year-old mother in her retirement village.”

But don’t go feeling sorry for Griffin. By her own admission, Trump’s revenge campaign against her was a blessing in disguise.

“No one in America wants anything to do with me but I’m selling out around the world,” she laughs. “Trump accidentally made me more famous!”

When it comes to speaking her mind, Griffin pulls no punches. She recently retracted her initial apology for the faux-beheading in an interview with Samantha Armytage and David Koch on Sunrise, in which she also accused Armytage of being “full of sh-t”.

“I got in trouble for yelling at someone named Sam!” she laughs, “It’s just fun to tell any broadcaster to cut the cr-p.”

That doesn’t mean she’s over her Trump encounter. In fact, her tour is based mainly around her experiences with the President, who she’s known for 20 years and describes as “aggressively stupid” – and worse.

“I’ll call him a Nazi, you can print that. I don’t care,” she says defiantly.

“People say, ‘He may have Nazi leanings’, no, he’s a Nazi. There’s a Nazi in the White House.”

Griffin plans to wage war on Trump and his administration with her tour, but also to poke fun at the firestorm that engulfed her mere months ago.

“You’ve got to laugh. I mean, I got a consolation note from Billy Bush out of the Access Hollywood video. That’s just funny. And I wasn’t grabbing any pussy! I just held up a fun shop mask with ketchup on it!”

Australian politicians shouldn’t get too comfortable either, as Griffin is remarkably well-versed in Australian affairs.

“You guys are a goldmine! This [postal] plebiscite is bullsh-t. Everyone knows old people aren’t used to gay marriage yet and they love post! Stamps and letters! I know the game.”

Openly anti-gay tennis legend Margaret Court should be feeling particularly nervous.

“Margaret Court is a dream for me. There will be a Margaret Court rant laced with profanity, I can promise you,” Griffin says.

The feisty redhead is remarkably optimistic about her future given she’s still a persona non grata in large parts of her home country.

“[After everything I went through] I realised I was on my own. I can’t wait to go on tour and get up on stage where no one can censor me,” she says.

“I’ve got my younger boyfriend who’s also my tour manager, two gay assistants and a drunk mother and there’s nothing we can’t do.”
