What medical condition does Gene Simmons have?
Gene Simmons’ atrial fibrillation diagnosis
- Simmons has publicly discussed living with atrial fibrillation (A‑fib), a heart condition that causes irregular heartbeat. In a 2016 appearance on The Doctors, he said he first noticed symptoms — dizziness, sweating, shortness of breath — during a concert about a decade earlier (AARP (advocacy group for seniors)).
- He has stated that rest and hydration help reduce recurring episodes (AARP).
The 2025 car crash medical emergency
- On October 7, 2025, Simmons crashed his black Lincoln Navigator into a parked car in Malibu. He reportedly told deputies he either passed out or fainted while driving (People (news magazine)).
- His wife, Shannon Tweed, later said doctors had recently changed his medications and advised increased water intake (AARP).
The implication: even a rock icon must contend with aging and chronic conditions that affect daily life.
Simmons’ on‑stage persona suggests invincibility, but his A‑fib condition and the single‑car crash reveal fragility. For a 75‑year‑old performer who still tours, the stakes are high: one fainting spell at the wheel can change everything.
Why is Gene Simmons’ tongue long?
- Simmons has a condition known as macroglossia, an enlarged tongue, which he has stated is natural and not a medical problem. The exact cause remains debated, but it contributes to his distinctive stage appearance.
The pattern: Simmons’ physical traits are both a trademark and a subject of public curiosity.
What happened to Gene Simmons?
Gene Simmons car crash in Malibu
- On October 7, 2025, Simmons was involved in a single‑vehicle crash on Pacific Coast Highway in Malibu. His SUV crossed several lanes before striking a parked car (ABC7 (local Los Angeles news station)).
- The Los Angeles County Sheriff’s Department confirmed he was transported to a hospital for medical treatment (ABC7).
Recovery and aftermath
- Simmons’ wife Shannon Tweed told NBC Los Angeles that he was recovering at home and that doctors had recently adjusted his medications (NBC News (national news network)).
- Simmons himself posted on X that he was “completely fine” and later joked the incident was a “slight fender bender” and that he is a “horrible driver” (AARP).
What this means: the incident is a stark reminder that medical management is as critical as stage performance for aging artists.
Who is the richest KISS band member?
Gene Simmons net worth compared to other KISS members
- With an estimated net worth of $400 million, Gene Simmons is the wealthiest member of KISS (AARP (advocacy group for seniors)).
- His fortune comes from music royalties, merchandise licensing, and business ventures that turned the KISS brand into a global marketing machine. Co‑founder Paul Stanley’s net worth is believed to be roughly half of Simmons’.
Sources of wealth beyond music
- Beyond KISS, Simmons has launched a record label, owns a talent management company, and appeared in films, television, and reality shows.
- His financial discipline is legendary within the industry: he famously owns the trademark for KISS and licenses the brand for everything from comic books to coffins.
The pattern: owning intellectual property and diversifying income streams creates lasting wealth beyond performance royalties.
Simmons’ wealth strategy — retaining branding rights and diversifying income streams — is a masterclass for musicians. For aspiring artists, the lesson is clear: own your intellectual property.

The catch: public admission of infidelity does not automatically undermine a long‑term partnership when both parties choose to stay together.
Was Cher in love with Gene Simmons?
- Cher and Simmons had a brief romantic relationship in the late 1970s. Cher has described it as a “fun fling” in interviews, indicating it was not a deep love affair.
The implication: Simmons’ public persona attracted Hollywood stars, but those connections were temporary.
