WhistlinDiesel Introduces Girlfriend Katie Miller, Confirms Split from Wife
WhistlinDiesel, the daredevil YouTuber known for pushing trucks and farm machinery to their limits, recently dropped a bombshell on his fans: he’s moved on. On June 10, 2022, he shared a photo on Instagram introducing his new girlfriend, Katie Miller. In the image, he’s casually seated in a Lamborghini sipping wine while Katie pretends to clean its wheels. His cheeky caption—“Sometimes when I’m in my air-conditioned shop sipping on $8 wine in my Lamborghini with my GF cleaning the wheels…”—not only introduced Katie but also confirmed that he and his wife, Rae (known online as Mrs. WhistlinDiesel), have separated (List23, KenyaSihami, BiographyPedia).
The relationship shift had been quietly brewing. Fans had noticed that videos featuring Rae stopped appearing in late 2021, and the couple even unfollowed each other on social media (FameShala, Heightline.com, KenyaSihami). Then, in mid-2022, Cody made things official with that now-viral Instagram post placing Katie in the spotlight (The SportsGrail, BiographyPedia, List23). While it’s clear that the two have separated, the legal status of their divorce remains unconfirmed (KenyaSihami, PelhamPlus, The SportsGrail).
Katie Miller herself remains a bit of a mystery. She’s described as a model, photographer, and social media personality—active on TikTok with a following north of 90,000—but she keeps her social media largely private (BiographyPedia, ABTC, AUBTU.BIZ).
With his new relationship made public, WhistlinDiesel appears to be embracing a fresh chapter—one that’s attracting as much attention as his high-voltage stunts.
