When a reality TV face trades Essex glamour for boxing gloves, it raises an eyebrow or two. Demi Sims did exactly that, swapping TOWIE for boxing gloves under her father’s training, and her story runs from early TOWIE appearances in 2014 to the ring, with a family web linking her to Joey Essex.

The pattern: seven core facts, one clear takeaway — Demi Sims is defined by both her reality TV origins and her family’s deep roots in boxing.

Is Demi Sims in a relationship?

As of early 2025, Demi Sims’ relationship status remains unconfirmed by the star herself. She has been linked in recent years to Jazz Saunders, a name that surfaces in fan discussions, but no official statement has been made.

Are Demi Sims and Jazz Saunders still together?

  • No public confirmation or denial from either party exists.
  • Media outlets describe the relationship as “unclear” — no joint appearances or statements since 2023.
  • Demi’s Instagram feed offers no clear signal of a current partner.

The implication: without a direct source, the question remains open. For fans tracking her personal life, it’s a waiting game.

Is anyone still together from any of the Love Islands?

This question sometimes gets confused with Demi Sims because of overlapping reality TV circles. Love Island couples have a mixed track record — some, like Molly-Mae Hague and Tommy Fury, have stayed together long-term, while others split within months. Demi Sims has not participated in Love Island, but her family’s Essex connections mean she often gets grouped into broader reality TV relationship chatter. Separate fact: Joey Essex, her cousin, appeared on Love Island in 2023 but has since parted ways with Jessy Potts.

The catch: Demi Sims’ story is a reminder that public interest in celebrity relationships rarely waits for confirmation.

Is Joey Essex related to Demi Sims?

Yes — Joey Essex and Demi Sims are cousins. The connection runs through the Sims family tree and explains why the two names frequently appear together in TOWIE headlines.

How is Tony Sims related to Joey Essex?

  • Tony Sims, Demi’s father, is a boxing trainer and the uncle of Joey Essex.
  • Joey Essex is the son of Tina Sims, making him a first cousin to Demi, Chloe, Frankie, and Charlie Sims.
  • The Sims family has trained major British boxers including Conor Benn and Anthony Joshua, according to DAZN (sports broadcaster).

What this means: Joey Essex’s fame in reality TV and Tony Sims’ career in professional boxing are two branches of the same family tree — a rare intersection of entertainment and sport.

The upshot

The Sims family’s boxing pedigree — training fighters like Conor Benn — gives Demi’s ring career a credibility that few reality stars can claim. Her father and uncle are established figures in the British boxing scene, not just armchair coaches.

What does Demi Sims’ dad do?

Demi Sims’ father is Tony Sims, a professional boxing trainer who has worked with elite fighters in the UK. He has been described in multiple sources as a central figure in the Sims family’s boxing tradition.

Demi Sims trained for boxing with her father Tony Sims before her ring debut.

— Closer magazine
  • Tony Sims trained Demi for her ring debut, according to Closer (celebrity magazine).
  • Her uncle, Peter Sims, is also linked to boxing coaching, as reported by DAZN.
  • The family’s reputation in boxing is established, with Tony and Peter Sims described as part of a “boxing dynasty” in British sport.

The pattern: Demi’s father is not just a parent — he’s a professional coach who turned her reality TV fame into a credible athletic move.

Are Chloe and Demi half sisters?

No — Chloe Sims and Demi Sims are full sisters. They share both parents and have appeared together on TOWIE as siblings, not half-siblings.

Do Chloe and Charlie Sims have the same mum?

  • Chloe Sims, Frankie Sims, Charlie Sims, and Demi Sims are all full siblings with the same mother and father.
  • No evidence suggests any of the four have different parents; media profiles consistently list them as siblings without qualification.
  • The family unit has been featured jointly in TOWIE storylines and spin-off projects like House of Sims.

Why this matters: the common assumption of half-sibling relationships in large blended families gets corrected here — the Sims siblings are a tight unit, not a patchwork.

The catch

Despite their close public image, the four Sims sisters have carved very different paths: Chloe as the long-time TOWIE fixture, Frankie as the more private sibling, Charlie as a model, and Demi as the boxer. The family label doesn’t erase individual careers.

How is Joey Essex so rich?

Joey Essex has accumulated wealth through a combination of reality TV appearances, brand endorsements, and business ventures. Estimates of his net worth vary, but media reports consistently place it in the millions.

Are Joey Essex and Jessy Potts still together?

  • Joey Essex and Jessy Potts split after appearing together on Love Island in 2023.
  • No official statement confirmed the exact date, but both have moved on publicly.
  • Jessy Potts has not commented on the reasons for the split.

Why did Jessy Potts and Joey split?

Sources close to the couple have suggested that distance and differing priorities contributed to the breakup. Neither party has confirmed specific details, leaving room for speculation in tabloid coverage.

Is Joey Essex single now?

As of early 2025, Joey Essex has not publicly confirmed a new relationship. His social media presence shows a focus on business projects and appearances rather than romance.

The trade-off: Joey’s wealth comes from multiple streams — TV salaries, clothing lines, and appearances — but his Love Island stint also showed that public relationships bring their own scrutiny, and sometimes that costs more than it earns.
