Beyonce has been accused of faking being black and hiding her true identity as an Italian woman named Ann.

The pop star, 38, has been caught up in a bizarre conspiracy theory which is being peddled by a congressional candidate in the US.

KW Miller, who is running to represent Florida's 18th Congressional District in America's November election, has made a series of twisted claims about the singer on Twitter.

Miller's false claims include a wild story that Beyonce is really of Italian descent and her real name is Ann Marie Lastrassi.

He tweeted: "Beyoncé is not even African American. She is faking this for exposure.

"Her real name is Ann Marie Lastrassi. She is Italian."

The politician went on to allege Beyonce's song Formation includes a number of cryptic coded messages and he claims she's a secret satanist.

He added: "You all do know that Beyoncé’s song “Formation” was a secret coded message to the globalists I certainly hope?

"The song clearly admitted that she was demonic and that she worshipped in the Satanist churches located in Alabama & Louisiana. She keeps Satanist symbols in her bag."

Followers on Twitter flocked to express their concerns over Miller's wild tweets, with many suggesting he seeks professional help.

One wrote: "I speak fluid sarcasm and this guy’s off his rocker."

Another tried to point out he seemed to have taken the conspiracy theory from a piece of fan fiction written about Beyonce.

They tweeted: "Sir this is a fanfiction written by a fan."

A third wrote: "This man is running for Congress and has unhealthy mental health issues. This isn't funny.

"He should not be anywhere near Congress. He needs help! This is NOT funny."
