Michael Jackson's huge fame sparked a string of wild conspiracy theories.

The singer is still one of the most famous men in the world more than a decade after his death.

Michael was 50 when he died from cardiac arrest in 2009, just weeks before he was due to kick off a string of sold out concerts in London.

From finding huge worldwide fame at the tender age of eight in band The Jackson 5 with his brothers, Michael became a fascinating and much-discussed subject, sparking many weird and wonderful conspiracy theories.

Here's a rundown of some of the strangest ones...

Michael and LaToya Jackson were the same person

One wild conspiracy theory suggested that Michael and his older sister LaToya were actually one and the same.

The siblings were born two years apart from each other and were pictured together on countless occasions before Michael's tragic death.

But that hasn't stopped conspiracy theorists from saying they're the same person.

The theory has been going around for years and has sparked many discussions on the internet.

Some people even suggested that they'd never seen Michael and LaToya together.

Those who believe it think that this one person faked Michael's death in 2009 because they grew tired of living a complicated double life and wanted to simply enjoy the rest of their years as LaToya.

One person who hit back at the theory suggested that never seeing Michael and LaToya together proved nothing because they knew Michael's brothers were real despite never seeing all of them together.

They obviously weren't a Jackson 5 fan.

Michael has sparked many conspiracy theories

Others said that Michael and LaToya only looked so similar because they'd both had the same nose job.

Michael wasn't his children's biological father

There are many conspiracy theories surrounding Michael's three children, Prince, Paris and Blanket, who has since renamed himself Bigi.

And many people believe that he wasn't their biological father.

Paris and Prince were born to mother Debbie Rowe, who met Michael when she was working as a nurse in a dermatology office, where he was being treated for vitiligo.

She said he was upset about his split from wife Lisa Marie Presley as he feared he may never become a father.

She proposed bearing his children, and by 1996 they were married and she was pregnant.

Some people believe Michael wasn't the biological father of his children

They divorced in 1999 and Michael took full responsibility for the children.

Michael's youngest was born via a surrogate, whose identity is still a secret.

He always insisted he was the biological father of all three of his children, but there are many alternative theories.

The most popular theory is that former child actor Mark Lester, who played Oliver in the 1968 film musical, is the dad.

He even claimed it himself in 2013 and said he'd have a DNA test to prove it.

The pair were close friends for decades and Mark claims he donated sperm to Michael before his first child was born.

Speaking in 2013, he said: "I wouldn't have a DNA test without the children's permission but when the children come of age, and it's not far away, and they decide they want me to do it then I will.

Michael died in 2009

"It is up to them. I don't want to tell them what to do. I just want to reconnect and be the godfather that Michael made me."

He added: "My 18-year-old daughter Olivia looks like Paris. People have also pointed out similarities between myself when I was younger and Prince Michael."

Michael faked his own death

Some fans believe that Michael faked his own death ... just like Elvis Presley.

Some people think that the King of Pop and the King of Rock 'n' Roll, who died in 1977, were holed up together in a bunker somewhere, peacefully living out their lives.

Is Michael holed up in a bunker with Elvis?

The wild internet theory said: "Surely you've heard of the secret, seven-storey-deep bunker that Elvis Presley had built underneath Graceland, prior to faking his own death? MJ lives there now with Elvis and certain other 'dead' celebrities. You don't have to be sad for him any more."

Michael was murdered

Kanye West recently claimed that Michael was actually murdered.

He died from cardiac arrest and his personal physician, Dr Conrad Murray, was later found guilty of involuntary manslaughter and sentenced to four years in prison.

But rapper Kanye believes a very different story.

In a bizarre since-deleted tweet, Kim Kardashian's husband penned: "MJ told you about Tommy before they killed him Kim saved my daughters life in the name of Jesus It’s Gods choice only I will live for my children Kris I’m in Cody if your not planning another one of your children’s playboy shoots."

Kanye claimed Michael was murdered

Kanye appeared to be referring to Sony CEO Tommy Mottola, who Michael had a highly publicised fallout with.

Michael had called Tommy "devilish" and "racist", but there is absolutely no evidence to suggest that Tommy was involved in Michael's death in any way.

Michael had bad blood with Sony for years.

The tension between them went into overdrive when the singer's expectations that the licences to the masters of his albums would revert to him fell through, thanks to a contract that had actually set the date for the reversion for several years later.

The star died of cardiac arrest

He demanded an early exit from his recording contract, and by 2002, Michael had become increasingly outspoken about the situation.

That prompted Sony to come to Tommy's defence, denying Michael's allegations and labelling him "spiteful".

Eventually, the label refused to renew their contract with Michael and alleged that they'd lost millions because the singer refused to go on tour for his album Invincible.

Michael's fans then began sharing old videos of the singer in which he'd referred to Tommy, who used to be married to Mariah Carey, as "the devil".
