The author of American Psycho says he's tired of all the protesting following Trump's inauguration.

Speaking at the launch of his new art exhibit in London this week, Bret Easton Ellis said he's no fan of the new president, but doesn't see what kind of change protesting will bring.

'I didn't vote Trump, I'm just saying the hysteria is bothering me a lot more than the reality of what he's doing,' Ellis told the Irish Examiner.

The American Psycho author put up a signed American Psycho poster for auction, signed 'Make America Great Again!' As of Friday afternoon, the highest bid was well over $1,000

'I don’t really know what the path to power is with protest, it’s done, this is where we are. If you wanna protest, protest the DNC, protest Hillary, protest whatever. But what you’re protesting here is an elected president,' he said, adding that he thinks the demonstrations are only 'aiding this divisiveness'.

'It happened. He was elected. He is our president. He’s moving very quickly. It’s bothering a lot of people. He is doing what he said he would do. He is elected.

'I do think there has been an overreaction to what’s going on. But that’s just endemic in the culture,' he said.

Ellis is the author of several critically-acclaimed novels including American Psycho (pictured) and The Rules of Attraction, both of which were made into movies

Ellis said he was mostly annoyed with all of the celebrities that have been continuing to speak out against Trump, like Meryl Streep.

Streep used her speech at the Golden Globes to rail against Trump, which Ellis says is exactly 'hashtag why Trump won'.

'When celebrities become these kind of strident, political advisers, wagging their finger, really people don’t buy it.

'It did not help Hillary Clinton at all having this mountain of celebrities on her side. Rejection, rejection,' be said.

Meanwhile, Ellis is using Trump's signature catchphrase to make a few bucks.

The author is auctioning off an American Psycho movie poster signed 'Make America Great Again!' on his website.

As of Friday afternoon, the highest bid for the item was $1,305 dollars. The online auction was set to end after 6pm Eastern Time.

Ellis was somewhat of a soothsayer during the campaign, tweeting in February 2016 about how friends in heavily-blue Los Angeles were planning to vote for Trump.

'Just back from a dinner in West Hollywood: shocked the majority of the table was voting for Trump but they would never admit it publicly,' Ellis wrote.

Ellis' new art show is in partnership with multimedia artist Alex Israel. It pairs photos with thought-provoking prose from Ellis, and runs at the Gagosian Gallery in London from February 3 to March 18.

Last year, Ellis tweeted about how he attended a dinner party in Los Angeles where the majority of attendees planned to vote for Trump
