You’ve probably heard it. That punchy, slightly aggressive, and incredibly catchy hook blaring through your TikTok feed or popping up on a Reels transition. It’s one of those songs that sticks in your brain like gum on a sidewalk. People keep searching for who sings liar liar truck on fire because, honestly, the song blew up so fast that the artist’s name almost got buried under the weight of a million lip-sync videos.
The track is actually titled "Liar Liar" and it’s performed by Cris MJ.
If that name sounds familiar, it should. Cris MJ is a massive deal in the Latin urban scene, specifically hailing from Chile. He’s the same guy who gave us "Una Noche en Medellín," a song so big it practically redefined the global reach of Chilean reggaeton. But "Liar Liar" (often associated with the "truck on fire" lyric) hit a different nerve. It tapped into that specific "revenge anthem" energy that the internet absolutely craves.
The Viral Mystery of the "Truck on Fire" Lyrics
Why the confusion? Well, the internet is a messy place. When a song goes viral, people often search for the most memorable lyric rather than the official title. In this case, the line "Liar, liar, truck on fire" isn't just a playground rhyme anymore; it’s a vibe.
Cris MJ released this track as part of a wave of new music that leans heavily into the "trap Latino" and modern reggaeton aesthetic. The production is crisp. It’s dark. It has that rhythmic bounce that makes it perfect for short-form video content. When you hear the specific cadence of "Liar, liar," it’s designed to be an earworm.
Music moves fast now.

Sometimes a song becomes a meme before it becomes a "hit" in the traditional sense. You might see a creator post a video about a breakup, a betrayal, or even just a funny fail, and they’ll overlay that specific "truck on fire" snippet. Suddenly, thousands of people are typing "who sings liar liar truck on fire" into Google because the snippet didn't tag the artist properly.
Cris MJ: From Chile to Global Charts
To understand the song, you kinda have to understand the man behind it. Cris MJ isn't some "one-hit wonder" TikTok creator. He’s a legitimate powerhouse. Born Christopher Álvarez García, he’s been a central figure in the "G-Pop" or Chilean urban movement.
The Chilean scene is fascinating. For years, it was overshadowed by Puerto Rico and Colombia. Then, suddenly, artists like Cris MJ, Pailita, and Polimá Westcoast started churning out tracks that felt grittier and more raw than the polished pop-reggaeton coming out of Miami.
"Liar Liar" represents a pivot. It shows his ability to cross over into English-speaking markets by using a hook that uses a familiar English idiom—the "Liar, liar, pants on fire" trope—but flipping it into something tougher. "Truck on fire" just sounds cooler, doesn't it? It adds a level of chaotic energy that fits his persona.
Why the Song Exploded on Social Media
There's a science to why this specific track worked.

- The Tempo: It sits right in that sweet spot for walking transitions.
- The Relatability: Everyone has a "liar" in their life.
- The Hook: It’s repetitive without being annoying (mostly).
Music labels now look for these "micro-moments" in songs. They don't just want a five-minute epic; they want fifteen seconds of gold that a teenager in Ohio can use to complain about their ex. Cris MJ delivered that perfectly.
Common Misconceptions and Cover Versions
Because the song is so popular, a lot of people think it might be a remix or a cover of an older track. It’s not. While the phrase "liar, liar" has been used in a dozen songs—from Dolly Parton to The Castaways—this specific "truck on fire" iteration is contemporary.
You’ll also find sped-up versions (nightcore) and slowed-down versions (reverb) all over YouTube. These edits often strip away the metadata, making it even harder for the average listener to find the original artist. If you’re listening to a version that sounds like a chipmunk on caffeine, it’s still Cris MJ, just digitally altered to bypass copyright filters or fit a specific "aesthetic."
Nuance matters here.
In the Latin music world, collaborations are everything. Cris MJ often works with other heavy hitters, but "Liar Liar" is a standout because it carries his signature flow—nasal, rhythmic, and unapologetically confident. If you like this, you’ll probably dig his other stuff like "Marisola" or "Daytona."

Tracking the Song's Performance
If we look at the data from Spotify and YouTube, "Liar Liar" isn't just a flash in the pan. It has millions of streams. It’s charting in countries that don’t even speak Spanish. That’s the power of a viral hook. It transcends language barriers. You don’t need to know exactly what he’s saying in the verses to feel the energy of the chorus.
The production value is also a step up. It doesn't sound like it was made in a bedroom. The bass is heavy enough for a club system, but clear enough for a phone speaker. That's a hard balance to hit.
What This Means for the Future of Latin Urban Music
We are seeing a shift. The "Big Three" of reggaeton (Bad Bunny, J Balvin, Karol G) are still at the top, but the new guard is coming from unexpected places like Santiago, Chile. Cris MJ is leading that charge. He’s showing that you don't need a massive American feature to go viral in the States; you just need a hook that people can't stop humming.
