He was Britain's most notorious serial killer - murdering five women and terrorising London in 1888, but was never caught.
But Gemma Collins believes she has discovered the identity of Jack the Ripper and is convinced she is related to him.
The former TOWIE star, 43, has been delving into her family tree while filming for an upcoming episode of BBC show Who Do You Think You Are?
And she soon discovered that she has ancestors who lived on Dorset Street in East London, where the infamous killer left some of his victims' mutilated corpses.
The body of Mary Jane Kelly - who is thought to be the final Ripper victim - was discovered in a property on the street in November 1888.

But Gemma doesn't think it's a coincidence her relatives lived on same street, as she believes the notorious butcher was none other than her great-great-grandfather, William Williams.
Speaking to The Daily Star, she explained: 'My great great grandfather worked in a workhouse and died there. I think that’s the reason they can’t find Jack The Ripper… because it was him.
'The writing is on the wall. It could only happen to me. It would be my luck that he would be one of my relatives.'
Gemma further laid out her theory to BBC News, as she insisted: 'No-one knows who the ripper was, but we lived next door to where a lot of his victims were being killed. You just don't know.
'I think I was related to him... It's just bizarre, isn't it? Could it be my family? Could he be alluded to be my family?'
However, the thought of being related to the brutal killer doesn't faze the reality star, as she admitted she was 'ecstatic' by the possibility and said it could explain parts of her personality.
She told the Star: 'I’m ecstatic. I always knew there was more to me and my family. The macabre of it – I just think it’s a hilarious story. Obviously the murders were terrible and I get that.
'But how could it be that my family were on the same street as Jack The Ripper’s victims? You just couldn’t make it up. You’ve got The GC and Jack The Ripper. I’m an unusual character and that’s definitely come from somewhere.'

Jack the Ripper's bloody crime wave took place between August 31 and November 9, 1888, with five women all brutally hacked to death (1891 engraving of murder)
Gemma now plans to use her psychic powers to get in touch with the Ripper's ghost via a séance, to learn more.
Jack the Ripper's bloody crime wave took place between August 31 and November 9, 1888, with five women all brutally hacked to death.
The victims - Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly - all worked as prostitutes and had their throats slashed, with three of them also having their organs removed.
From one of the women, half a kidney was removed and sent to police officers along with a series of notes, signed off from the Ripper.
But mistakes were made during initial inquiries into the murders, with no fingerprinting being able to distinguish the difference between even human and animal blood, let alone the differences between people.
This means the true identity of Jack the Ripper could never be revealed, leaving it as one of the world's unsolved cold cases.
There are many theories as to who the infamous serial killer was, from Queen Victoria's surgeon Sir John Williams, who had a surgery in Whitechapel at the time, to her Grandson Prince Albert Victor who was taken to an asylum and died in 1892.
Gemma's episode of Who Do You Think You Are? also sees her reunite with her mother's cousin, Christine, who the family had lost touch with.

She also learned more about her biological grandparents, as her mother Joan (pictured) had been fostered as a child and said it had been 'very cathartic' for her mum to get answers
She said it was 'unbelievable' to learn that Christine only lived 20 minutes away from their house, and added: 'What a shocker it’s been for them in their life to wake up and be told "You’re related to the GC".'
She also learned more about her biological grandparents, as her mother Joan had been fostered as a child.
Historians discovered that Joan's mother hadn't abandoned her, but was likely taken from her by the state.
Gemma admitted it was 'bittersweet' to discover the details, but that it had been 'very cathartic' for her mother to get answers she'd been looking for.
Gemma's Who Do You Think You Are episode airs Thursday 26 September at 9pm on BBC One.
