Lorde is a 's**thead' who should start a 'F**k the Jews' world tour - Howard Stern

US shock jock Howard Stern has labelled Kiwi singer Lorde a 'shithead' who should start a 'F**k the Jews' world tour.

He's the latest pro-Israel voice to unload on the 21-year-old, who last month announced a show in Tel Aviv, then cancelled it after "an overwhelming number of messages and letters" asking her not to perform.

Since cancelling the concert, the 'Royals' singer has been called a "bigot" by US comedian Roseanne Barr and targeted in a full-page advert in the Washington Post.

Stern, 63, gave his views on Lorde's decision earlier this month on his Sirius XM Radio show.

"Anti-semitism is on the rise. I am so f**king sick of it," he told listeners, before calling Lorde a "shithead".

"F**k her. One f**king hit song this girl is living off. She has no problem with Russia. The only place in the world where she can't play is Israel. So what do you think's going on? What's the one thing about Israel that's different than all other places? There's Jews there."

Stern said he hopes Lorde "has a good time in Russia", then claimed she only had one hit song.

"Her song is 'Royal'. She must do 'Royal' for two hours," he said, getting the name of her biggest hit wrong.

Lorde has since had two more top 10 singles on the US Billboard charts - 'Team' and 'Green Light'. The latter's parent album Melodrama hit number one in the US, Canada, Australia and New Zealand.

Stern suggests a 'F**k the Jews' world tour

Lorde's move has been welcomed by dozens of prominent singers and entertainers, including Roger Waters - arguably the loudest celebrity voice of the Boycott, Divestment and Sanctions (BDS) movement.

Stern's foul-mouthed tirade didn't exclude the ex-Pink Floyd frontman.

"Rogers Waters, that f**king moron.  He looked around the world and he's completely hyper-focused on Israel, not hyper-focused on Russia, that is planting all kinds of problems throughout the world, all kinds of terrorism, f**king with us with our elections.

"Lorde and Roger Waters should get married and start a 'F**k the Jews' world tour."

A co-host suggested Lorde play in Gaza instead, where an Israeli blockade has been in place for more than two decades restricting movement and undermining living conditions, according to the United Nations Office for the Coordination of Humanitarian Affairs.

Stern quipped she'd probably be shot "on sight" if she showed off her belly.

"I want to hear Katy Perry's view on Syria before I do anything."

Stern has long been a campaigner for free speech, and racked up millions of dollars in fines during a 30-year career on FM radio, before going digital.

Waters, whose heavily politicised latest album Is This the Life We Really Want? tackles Israel and Donald Trump, is scheduled to play two shows in Auckland later this month.
