Who is JJ Slater?
What is JJ Slater’s background?
- JJ Slater is a British fashion entrepreneur and reality TV personality who first rose to public attention through Married at First Sight UK in 2023, where he joined as an intruder groom (Metro).
- His full name is John Joe Slater; he was born in Florida but is also based in Essex (Cosmopolitan UK).
- He runs the clothing brand Fully Blessed and has described himself as a founder based between Florida and Essex, also noting he was diagnosed with Type 1 diabetes (Cosmopolitan UK).
What age is JJ Slater?
- JJ Slater is 33 as of early 2026. Heat reports his birth date as 13 June 1992 (Heat World). Cosmpolitan UK also cites 13 June 1992 and noted he was 30 in its October 2023 profile (Cosmopolitan UK).
- Metro described him as 31 in February 2024 (Metro), which aligns with a mid-1992 birth.
The catch: while multiple publications agree on the birth date, no birth certificate or official record has been directly published, making the figure consistent but not independently verifiable via primary sources.
JJ Slater’s age is reliably triangulated across three tier-2 publications, but the absence of a Wikipedia or official bio page means his birth record remains in secondary-source territory. For a public figure with no verified government document tied to his name, the consensus at 33 is the best available figure.
What does JJ Slater do for work?
Fashion entrepreneurship
- JJ Slater is the founder of Fully Blessed, a clothing brand he operates from Essex (Cosmopolitan UK). Famous Birthdays identifies the brand as Fully Blessed Co. and also notes he is a co-owner of Pink Restaurant and Nightclub in Essex (Famous Birthdays).
- Despite the brand’s public visibility — Slater wears it in social media posts — The Sun reported that company documents filed for Fully Blessed showed a loss of £31,006 for the year ending 31 July 2023, and that the business had not yet reported a profit and had no stock for that filing period (The Sun).
- He also serves as a NovaMEN ambassador, a role that pairs his reality TV profile with menswear promotion.
Reality television
- His primary TV exposure came as an intruder groom on Married at First Sight UK in 2023 (Famous Birthdays). The show’s format introduces late-arriving participants mid-experiment, which generated immediate tabloid interest.
- Social media follows expanded quickly: his Instagram account @johnjoeslater now sits at 122K followers, with TikTok at 59.1K.
The gap between brand visibility and financial performance matters. If Fully Blessed’s filings continue to show losses, Slater’s influencer income and media appearances become the primary revenue drivers — a pattern common among reality TV entrepreneurs whose fame pre-dates their business model.
What is JJ Slater’s net worth?
- Exact net worth is not publicly confirmed; estimates vary widely.
- Metro reported a figure of $750,000 (£591,000), attributing the number to the aggregator site Newsunzip (Metro). Metro explicitly noted that this is an unverified secondary estimate rather than a confirmed filing.
- His income streams include his clothing brand, social media partnerships, and TV appearance fees. No verified statement from Slater, his accountant, or Companies House has disclosed a specific net worth figure.
The trade-off: the reported $750,000 figure circulates widely online, but a company filing showing losses and no stock suggests the actual liquidity picture is more modest. For a fashion entrepreneur with high visibility and low documented revenue, net worth estimates are speculative.
Who is JJ Slater with now?
Has JJ Slater got a new girlfriend?
- Yes. JJ Slater moved on from Katie Price with a tattooed model, as reported by The Sun in March 2026 (The Sun). Social media activity — including new photographs and interactions — corroborates the relationship.
- His new partner has not been named in mainstream reporting as of the publication date, and Slater himself has not made a public announcement beyond indirect social media signals.
Are Katie and JJ still together?
- No. Katie Price and JJ Slater split prior to 2026. Geo News reported that the relationship ended with Price ending the romance (Metro). Neither party has given a detailed public statement about the breakup.
- The pair were first linked in late 2023 or early 2024 — Closer covered their social media posts showing ski trips and nights out together (Closer).
The pattern: Slater’s romantic timeline moves in lockstep with his TV visibility. The relationship with Price generated the bulk of his media coverage between 2024 and 2025; the new relationship in 2026 marks a transition from “Katie Price’s ex” to a standalone public figure.
Why did Katie and JJ Slater break up?
- The breakup reasons have not been explicitly stated by either party.
- Media reports suggest the relationship ended before March 2026, but no public statements from Katie Price or JJ Slater detail the cause.
- Speculation in tabloids has focused on lifestyle differences and career priorities, but these remain unconfirmed.
The absence of a definitive breakup statement leaves a gap that tabloid speculation fills. For Slater, this ambiguity works against the clean narrative control that established public figures typically maintain. The lack of a joint or individual statement means the breakup chronology relies on inference from social media silence — a low-certainty signal.
