Teddi Mellencamp (full name Teddi Mellencamp Arroyave) is an American reality TV personality, podcast host, and accountability-focused fitness/lifestyle coach best known from The Real Housewives of Beverly Hills (RHOBH).

Who she is (Quick Scoop)

  • American TV personality, former RHOBH cast member, and daughter of rock musician John Mellencamp.
  • Runs the lifestyle and weight-loss accountability program “All In by Teddi.”
  • Co‑hosts the pop‑culture and Bravo‑focused podcast Two T’s in a Pod.
  • Known online for her straight‑talk, “hold you accountable ” coaching persona and very public reality‑TV feuds.

Background and early life

  • Born July 1, 1981, in Bloomington, Indiana, USA.
  • Grew up in Hilton Head Island, South Carolina, where she became a highly competitive equestrian from a young age.
  • After winning a major stakes class in her final junior year, she moved to Los Angeles at 17, working in the mailrooms at talent agencies CAA and UTA while trying to break into acting.

Career: TV, fitness, and media

Reality TV and on‑screen work

  • RHOBH: Main cast seasons 8–10 (2017–2020), later a guest in seasons 11–13, appearing in over 70 episodes.
  • Other TV appearances include:
    • Flipping Out and Vanderpump Rules as herself.
* _Celebrity Family Feud_ and _Celebrity Big Brother_ (she finished 11th).

* Contestant on _Name That Tune_ and later _The Masked Singer_ (2026).

Her social media posts often reference Bravo drama and RHOBH dynamics, and she engages openly with fans and critics about episodes and conflicts.

“All In by Teddi” and fitness brand

  • Founder of “All In by Teddi,” a coaching program centered on daily check‑ins, strict meal and workout plans, and accountability.
  • Marketed as a tough‑love, results‑driven program for weight loss and lifestyle change.

However, the program has drawn significant criticism:

  • Critiques focus on alleged extreme low‑calorie plans (reports of sub‑700‑calorie days), uniform menus for all clients, and lack of trained medical oversight.
  • Commentators and some former participants have questioned the safety and transparency of the methods, especially for people with health issues or a history of disordered eating.

Podcasting and online presence

  • Co‑hosts Two T’s in a Pod , a podcast where she and co‑host Tamra Judge talk Bravo shows, reality gossip, and personal life updates.
  • Active on X (Twitter) and other platforms; often live‑tweets RHOBH episodes and reacts to fan discourse and cast drama.

Personal life

  • Birth name: Teddi Jo Mellencamp.
  • Married to businessman Edwin Arroyave since July 7, 2011; they have children together.
  • Previously married to Matthew Robertson.

Her family background and the “Mellencamp” name often come up in interviews, particularly around her relationship with her father, John Mellencamp, and how she built her own identity in reality TV and fitness rather than in music.

Health and latest news

  • In March 2022, Teddi was diagnosed with stage II melanoma (a form of skin cancer), which was surgically removed.
  • By early 2025 she revealed that the melanoma had progressed, with multiple brain tumors causing severe headaches; her cancer was re‑staged to stage IV.
  • In late 2025, she said doctors had found “no detectable cancer,” describing herself as “cancer‑free” while still undergoing immunotherapy for her stage IV melanoma history.
  • She has discussed the experience in a candid, sometimes darkly humorous way on her podcast and in interviews, including emotional conversations with her father about mortality and burial plans that she later clarified were meant in a light‑hearted context.

Her health journey has become a major part of how fans talk about her now, shifting some of the focus from pure RHOBH drama to resilience, early detection, and ongoing treatment.
