Seven key facts about Roxy Horner, drawn from verified sources:

What illness does Roxy Horner have?

What is type 1 diabetes?

• Type 1 diabetes is an autoimmune condition where the pancreas produces little to no insulin. Horner was diagnosed in May 2021, a month before her 30th birthday, according to Diabetes UK (UK’s leading diabetes charity).
• She told Diabetes UK that symptoms included extreme fatigue, poor memory, inability to focus, vomiting, and near-constant exhaustion before she took herself to A&E.

How does pregnancy affect type 1 diabetes?

• Horner has spoken about managing glucose levels during pregnancy. She wore a Dexcom G7 continuous glucose monitor and used an Omnipod 5 insulin pump, as reported by The Times (UK broadsheet).
• She admitted in The Times that she “worried about being a burden” and that the condition made her anxious at her own wedding — but she decorated her glucose monitor with stick‑on pearls.

Did Leonardo DiCaprio date Roxy Horner?

Who was the love of Leonardo DiCaprio’s life?

• Multiple reports place Horner as one of DiCaprio’s relationships in 2016‑2017. The Times alluded to this in its biographical coverage of Horner. No definitive statement from DiCaprio or Horner has been made publicly.
• DiCaprio’s “love of his life” is a topic of persistent tabloid speculation, but no single person has been universally identified. Horner was reportedly part of his social circle during that period.

What is Leo DiCaprio diagnosed with?

• There is no verifiable public information that Leonardo DiCaprio has a diagnosed medical condition. This question often arises from confusion with Horner’s own diabetes diagnosis.

The catch: the DiCaprio‑Horner connection is thin — two years of rumoured dating that neither party has confirmed. Readers looking for dramatic romance may find more substance in her relationship with Jack Whitehall.

How did Roxy Horner become famous?

How did she start modeling?
