You remember Cindy Lou Who. Or maybe you remember the raccoon-eyed, fishnet-wearing Jenny Humphrey from Gossip Girl. Either way, if you haven’t seen a photo of Taylor Momsen lately, you’re in for a shock. The frontwoman of The Pretty Reckless didn't just grow up; she apparently turned into a high-performance athlete while no one was looking. At the 2025 MTV VMAs, she walked out in a black bralette and a leather skirt, and the internet basically stopped. Why? Because Taylor Momsen abs have become a legitimate phenomenon.
It wasn’t just "thin rocker" vibes. It was shredded. We’re talking deep-cut obliques and a visible six-pack that looks like it was carved out of marble. People on Reddit were literally debating if she used contour makeup to draw them on (spoiler: she didn't).

The Real Secret Behind the Transformation
Honestly, we’ve all seen celebrities claim they just "drink water and go for walks" to stay fit. It's annoying. Momsen, however, is refreshingly blunt about the fact that she works her tail off. She told Page Six on the red carpet that she tries to do something every single day. Consistency. That’s the boring, unsexy truth.
But what is she actually doing?
Lately, she’s been obsessed with boxing. She even joked about wanting to be the real-life Buffy the Vampire Slayer. If you’ve ever hit a heavy bag, you know it’s not just about your arms. Every time you throw a cross or a hook, your core has to rotate and stabilize. It’s an accidental ab workout that burns more calories than a treadmill ever could.
Not Just Sit-ups and Salads
If you think she's just doing crunches, you're wrong. Momsen has been seen on TikTok and Instagram doing some pretty unconventional stuff. We're talking about hitting a steel mace against a massive tractor tire. That kind of functional training builds the "thick" core muscles that actually show through, rather than just looking lean.

- The Workout Mix: It's a blend of boxing, heavy lifting, and "mental health" movement.
- The Motivation: She’s been open about using fitness to manage grief and depression, especially after losing friends like Chris Cornell.
- The Discipline: She posted on Facebook that her life is basically "workout, record, repeat."
The physical change is a byproduct of a lifestyle shift. When The Pretty Reckless started touring with legends like AC/DC on their Power Up tour, the physical demand went through the roof. You can’t command a stadium stage for two hours if you’re not in peak condition.
Why Taylor Momsen Abs Look Different
Genetics play a huge role, sure. Some people have "long" midsections that show muscle definition more easily. But the level of definition Momsen is sporting right now—especially in the BTS shots for the "For I Am Death" music video—requires a very low body fat percentage and significant muscle mass.
She isn't just "skinny." You can see the serratus anterior muscles (those finger-like muscles on the ribs). That only happens when you’re doing heavy compound movements and high-intensity interval training (HIIT).
The Diet Side of the Coin
She hasn't released a full "What I Eat in a Day" video yet, but we can piece it together. In various interviews, she’s mentioned sticking to healthy fats and high protein. Think salmon, avocados, and lots of greens. Interestingly, she told Alex Cooper on Call Her Daddy that her brain doesn't even wake up until 7 PM. She’s a total night owl. This suggests she might inadvertently be doing a form of intermittent fasting, eating her meals later in the day to match her rockstar schedule.
There's no magic pill here. It’s just a 32-year-old woman who decided to get strong.
How to Actually Get Results Like This
If you're looking at those photos and thinking, "I want that," you have to realize she’s training like a pro. Most people get it wrong by doing 500 crunches. That won't work.
- Stop focusing on isolation. Switch to "rotational" power. Boxing, medicine ball slams, and even woodchoppers with a cable machine are better for those "rockstar" obliques.
- Lift heavy. You need muscle mass to have definition. If you only do cardio, you'll just look thin, not "ripped."
- Clean up the "hidden" sugars. Rockstars aren't exactly known for kale smoothies, but Momsen has clearly traded the party lifestyle for a gym-rat mentality.
- Find a "Why." For her, it was surviving grief and preparing for a massive world tour. If you don't have a reason to show up when you're tired, you won't.
The Taylor Momsen abs era is a reminder that transformations take time. She didn't look like this three years ago. It took a "new chapter" and a lot of sweat in a dark boxing gym. If you want to see the progress for yourself, go watch the "For I Am Death" video. Just be prepared to feel like you should probably go do some planks immediately after.
