Teddi Mellencamp Arroyave (born Theodora Diane Mellencamp) is an American reality TV personality, entrepreneur, and wellness coach. Born on September 1, 1981, in Bloomington, Indiana, Teddi is the daughter of legendary rock musician John Mellencamp and his former wife, Vicky Granucci. While her father’s fame cast a long shadow, Teddi carved her own path, first stepping into the spotlight as a cast member on RHOBH in 2018.

But Teddi isn’t just a reality star. She’s a mother of three, a wife, and the founder of All In by Teddi, an accountability coaching program designed to help people achieve their fitness and wellness goals. Recently, she’s also become a vocal advocate for melanoma awareness after her own skin cancer diagnosis in 2022. Teddi’s journey is one of resilience, reinvention, and using her voice to empower others.

Early Life: Growing Up as John Mellencamp’s Daughter

Teddi’s childhood was far from ordinary. Her father, John Mellencamp, is a Grammy-winning artist known for hits like Jack & Diane and Small Town. Growing up in Indiana, Teddi split her time between her parents after their divorce. Despite her father’s fame, Teddi has often described her upbringing as “humble” and grounded.

In interviews, Teddi has shared that her parents instilled strong Midwestern values in her—hard work, honesty, and staying true to oneself. These lessons would later shape her career and personal brand. However, being the child of a celebrity wasn’t always easy. Teddi faced public scrutiny from a young age, something she’s openly discussed on her podcast, Two Ts in a Pod, co-hosted with fellow RHOBH alum Tamra Judge.

Rise to Fame: The Real Housewives of Beverly Hills

Teddi joined RHOBH in Season 8, replacing longtime cast member Lisa Vanderpump. Known for her calm demeanor and “voice of reason” role, Teddi quickly became a fan favorite. Unlike some of her co-stars, she avoided drama and focused on building genuine friendships, particularly with Kyle Richards.

However, her time on the show wasn’t without controversy. Teddi faced criticism for her strict accountability coaching methods and her involvement in the infamous “Puppygate” scandal, which centered around accusations that co-star Lisa Vanderpump leaked stories to the press. Teddi left the show after Season 10 in 2021, citing a desire to focus on her family and business.

Reflecting on her RHOBH experience, Teddi has said, “Reality TV taught me a lot about myself. It pushed me out of my comfort zone, but it also showed me what truly matters—my family and helping others.”

All In by Teddi: Building an Accountability Empire

While still on RHOBH, Teddi launched All In by Teddi in 2019, a wellness program combining personalized coaching, nutrition plans, and daily check-ins to help clients stay “accountable” to their goals. The program gained traction quickly, with clients praising its structured yet supportive approach.

But success came with challenges. In 2021, Teddi faced backlash when former clients accused the program of promoting restrictive eating habits. Teddi addressed the criticism head-on, revamping the program to emphasize balance and mental health. “I’ve learned that accountability isn’t about perfection—it’s about progress,” she said in a YouTube Q&A.

Today, All In by Teddi continues to thrive, with a focus on holistic wellness, including fitness, nutrition, and mindfulness. Teddi’s transparency about her own struggles with body image and self-doubt has resonated with thousands of followers.

Personal Life: Marriage, Motherhood, and Health Battles

Teddi married Edwin Arroyave, a security software CEO, in 2011. The couple has three children: Slate, Cruz, and Dove. Teddi often shares glimpses of her family life on Instagram, showcasing chaotic school mornings, family vacations, and heartfelt moments with her kids.

In 2022, Teddi’s life took a serious turn when she was diagnosed with melanoma, a dangerous form of skin cancer. She discovered the cancerous mole on her back during a routine checkup and underwent surgery to remove it. Since then, Teddi has become an outspoken advocate for skin cancer awareness, urging fans to wear sunscreen and get regular skin checks.

“Cancer doesn’t care how old you are or how busy you are,” Teddi wrote on Instagram. “Getting that diagnosis was terrifying, but it taught me to prioritize my health and speak up for others.”

Recent Endeavors: Podcasting, Advocacy, and Beyond

Post-RHOBH, Teddi has stayed busy. She co-hosts the podcast Two Ts in a Pod with Tamra Judge, where the duo discusses reality TV, wellness, and life behind the scenes. The podcast has developed a loyal following for its humor and candid conversations.

Teddi has also partnered with organizations like the Skin Cancer Foundation to raise awareness about melanoma. In 2023, she launched a campaign called #CheckYourSkin, sharing educational content and personal stories to encourage early detection.

Additionally, Teddi has dipped her toes into acting, appearing in Hallmark Channel’s A Royal Christmas Crush in 2023. While she jokes that acting is “way harder than reality TV,” fans loved seeing her in a new light.

Teddi Mellencamp’s Legacy: More Than a Reality Star

Teddi’s journey is a testament to the power of reinvention. From reality TV to entrepreneurship and advocacy, she’s proven that authenticity and resilience can open new doors. While critics once labeled her “boring” on RHOBH, Teddi has embraced her low-key persona, using her platform to uplift others rather than chase drama.

Her focus on health and accountability—both for herself and her clients—has inspired many. As she told People magazine, “I want people to know they’re not alone in their struggles. Whether it’s fitness, mental health, or a cancer diagnosis, we’re all in this together.”
