Jenna Jameson, one of the world’s most famous porn stars, has launched into a tirade against Muslims and an apparent defence of the Ku Klux Klan.

Jameson’s anti-Muslim Twitter rant, which has taken place for the best part of 48 hours, was sparked by her defence of President Donald Trump.

The performer, who has appeared in almost 200 adult films, defended Mr Trump’s decision to cite a Swedish terrorist attack which appears never to have happened. The President sparked outrage and disbelief for the remark, prompting Sweden’s former Prime Minister to ask: “What has he been smoking?”

But this did not stop Jameson, an outspoken Trump supporter who has a photo of the pair together as her Twitter photo, from claiming Sweden was “a land of violence and fear”. She also suggested Chelsea Clinton, the daughter of Mr Trump’s former Democrat presidential rival, take a “quick trip” to Sweden to properly understand what the women in the country are dealing with.

When probed about whether she had a problem with multicultural countries, Jameson said: “I have a problem with roving Muslim rape gangs... call me crazy.”

“Listen you flat out idiot, Sweden is the rape capital of the world since it opened its arms to these sharia loving psychos #faceit,” she continued, citing a statistic that bears no relation to reality.

This remark was followed by a series of unfounded assertions about migrant crime in the country and rebukes against “lefties”, “liberals” and the “mainstream media”.

Later in the lengthy Twitter exchange, Jameson appeared to suggest the Ku Klux Klan was not as bad as “Muslim rape gangs”.

"Do the klu klux klan follow a religion that orders the death of apostates? When was the last time we saw a klan member blow up infidels?" Jameson asked.

Nevertheless, Jameson, who announced she was retiring from the adult entertainment industry in 2008, later denied she had defended the KKK - a secret society in the south of America that focuses on white supremacy. She dubbed a news report declaring she defended them “fake news”.

Jameson also sought to defend Milo Yiannopoulos, the former Breitbart senior editor who resigned on Tuesday after apparently pro-paedophilia remarks resurfaced in an old podcast. The far-right provocateur, who has apologised for the remarks and insisted he does not “support paedophilia”, has had his book deal pulled and an appearance at a major US political conference dropped.

“Because they lead the smear campaign against Milo, who is an important conservative leader for this generation. #istandwithmilo,” Jameson said.

Throughout the exchange, Jameson, who announced she converted to Judaism to marry her Israeli boyfriend Lior Bitton last year, used her religion to defend her inflammatory opinions. In recent times, Jameson has become known for sharing her provocative and at time far-right opinions about Muslims and immigrants on Twitter.
