Jacinda Ardern asked for advice for US presidential-hopeful Kanye West

Jacinda Ardern doesn't "have any advice" for US presidential-hopeful Kanye West.

West announced his bid for president on Saturday (local time), saying it's time to "realise the promise of America by trusting God, unifying our vision and building our future".

But the Prime Minister appeared amused when asked if she had any advice for him and said she doesn't "have any inside information" on his run for president.

"You're asking me what my advice for Kanye West is?" she said during a press conference on Monday.

"It may not surprise you. I can't say I have any advice for Kanye West for running for the American presidency."

West already has several celebrity supporters, including his wife Kim Kardashian, Elon Musk and rapper Ty Dolla Sign.

Soon after his announcement, outspoken Tesla CEO Musk wrote that West "had his full support", while Ty Dolla Sign tweeted: "Ye for President."

West first announced his presidential intentions during a speech at the MTV Video Music Awards in 2015.

"I don't know what I'm fitting to lose after this, it don't matter though, because it ain't about me, it's about new ideas, bro, people with ideas, people who believe in truth," he said.

"And yes, as you probably could've guessed by this moment, I have decided in 2020 to run for president."

Since then, West has publicly expressed his support for US President Donald Trump on several occasions, including wearing a 'Make America Great Again' hat and visiting him at the White House. At the time of West's 2015 announcement, Trump called him a "nice guy" and said he "hoped to run against him one day".
