If you close your eyes and think of Cindy Lou Who, you probably see a tiny girl with a pink nightgown and hair gravity-defying enough to make a structural engineer sweat. She was the moral compass of Whoville. She was the one who looked at a green, hairy hermit and saw a soul worth saving.
That was 2000. It’s now 2026, and the girl behind those giant blue eyes, Taylor Momsen, has lived about four different lifetimes since she shared a plate of roast beast with Jim Carrey.
Honestly, the "where are they now" trope usually ends in one of two ways: a quiet life in the suburbs or a tragic downward spiral. Momsen took a third door. She traded the pigtails for heavy kohl eyeliner, high-fashion runways, and a career as one of the most respected frontwomen in modern rock. But recently, something shifted. After years of distance, the girl who played Cindy Lou Who now seems to be embracing the Whoville ghost she tried so hard to outrun.
The Long Road from Whoville to Rock Fest
For a long time, if you asked Taylor Momsen about the Grinch, you’d get a polite but brief answer. She was seven when that movie came out. By twelve, she was auditioning for Hannah Montana (she was in the top three, but lost to Miley Cyrus). By fourteen, she was "Little J," Jenny Humphrey, on the cultural juggernaut Gossip Girl.
She was a star, but she was miserable.
"I didn't fit in," she admitted recently on the Podcrushed podcast. She was the "Grinch girl" at school and the "young girl" on set. While her peers were worried about prom, Momsen was dreaming of Soundgarden. In 2011, she did the unthinkable in Hollywood: she quit. She begged the Gossip Girl writers to let her out of her contract so she could tour with her band, The Pretty Reckless.

They didn't just let her go; they wrote her out so she could follow her "dream." Most people thought it was a phase. It wasn't.
Reclaiming "Where Are You Christmas?"
Fast forward to the 2025 holiday season, and Momsen did something nobody expected. She released a holiday EP titled Taylor Momsen’s Pretty Reckless Christmas. The lead single? A dark, soaring rock reimagining of "Where Are You Christmas?"—the very song she sang as a seven-year-old in Whoville.
Seeing Cindy Lou Who now performing that track is a trip. The music video even starts with a vintage clip of her on The Tonight Show with Jay Leno from the original press tour. It's a full-circle moment that feels less like a cash grab and more like a woman finally being at peace with her past. She even performed the song's final notes—which she hadn't touched in 25 years—while wearing a vivid red Christian Siriano dress.
What Taylor Momsen is Doing in 2026
If you’re looking for her on a movie screen, don't bother. Momsen has been retired from acting for over a decade. Her "now" is strictly loud, electric, and fueled by stadium crowds.
As of January 2026, The Pretty Reckless is back on the road. They aren't just playing clubs, either. They are the primary support for AC/DC on the North American leg of the "Power Up" world tour.

The "Batgirl" Incident
Touring with AC/DC hasn't been without its drama. During a 2024 show in Seville, Spain, a literal bat flew onto the stage and bit Momsen’s leg while she was performing. Most people would scream and run. Momsen just kept singing, eventually getting a series of rabies shots that lasted weeks.
The legends in AC/DC—Angus Young and Brian Johnson—found it hilarious. They’ve since nicknamed her "Batgirl" and even threw her a bat-themed birthday party with a giant bat cake and a tiara made of bat horns.
- Current Tour: Opening for AC/DC across U.S. stadiums (July - September 2026).
- Festival Circuit: Headlining Rock Fest 2026 in Wisconsin alongside Gojira and Limp Bizkit.
- New Music: Rumors are swirling about a fifth studio album following the success of Death by Rock and Roll.
Meeting the Grinch Again
One of the most heartwarming moments for fans of the 2000 film happened late last year at the Rock and Roll Hall of Fame induction ceremony. Momsen was there to honor Soundgarden—a band she essentially credits with saving her life.
Who was the official inductor? Jim Carrey.
It was their first time seeing each other since they wrapped filming 25 years ago. Momsen described the reunion as "coming home." She said that when she hugged him, it felt like family. Despite the massive gap in time and the radical shift in her persona, that connection to Whoville remains the foundation of her career.

Why the Cindy Lou Who Legacy Still Matters
It’s easy to dismiss child stardom as a fluke, but Momsen’s trajectory proves otherwise. She didn't "disappear." She evolved.
The reason people are so obsessed with Cindy Lou Who now isn't just nostalgia. It's the rarity of seeing a child star navigate the "dark side" of the industry and come out the other side as a legitimate, respected artist. She holds the record for the most No. 1 singles on Billboard’s Mainstream Rock chart for a female-fronted band.
She isn't just "the girl from the Grinch" anymore. She's a rock icon who happens to have a very famous Christmas movie on her resume.
