She voiced M3gan. Now her breakup anthem is blowing up TikTok.

“In Texas, we have this saying called ‘Go big or go home,’” says Jenna Davis. She’s going big.

Let’s take a look at a day in her life — June 27, 2025 — for proof: she returned as the voice of the AI robot killer M3gan in M3GAN 2.0, which opened in theaters nationwide, and debuted her debut country album, Where Did That Girl Go? Phew!

If Davis’ big day hasn’t landed on your radar yet, there’s still a chance you’ve heard the 21-year-old’s voice before, in the horror-comedy franchise or on the radio. But content creation is where she’s found the most success so far. With a combined 10.4 million followers across YouTube, Instagram or TikTok, she’s been growing and tending to her social media following, all the while pursuing the creative projects that she’s most passionate about.

'A dorky little girl'

Davis’s first brush with social media stardom came in her childhood, when her voice teacher mom recorded videos of her singing covers in her apartment’s parking garage, then uploaded them to Instagram. In one viral video from 2018, the then 14-year-old, wearing a denim jacket and rocking a severe side part, makes intense eye contact with the camera as she soulfully sings “Jealous” by Labrinth.

Davis says she learned her lesson about the eye contact — commenters used to say she was “staring into their souls” — but is well aware that her adolescent awkwardness added to her charm back in the day.

“People just started to catch on and watch my content because I was a dorky little girl who didn’t care what I looked like — rocking pigtails or weird miscolored outfits and just being me,” she tells Yahoo. “I would look right into the camera and sing my little heart out.”

Davis booked a few gigs over the years as an actress in shows like Raven’s Home and Treehouse Detectives. As her follower count grew, she wanted to share more than just singing videos online. That’s when she started acting more like a traditional influencer, attempting viral challenges and uploading prank videos.

Some of her most popular videos include “I SPENT THE NIGHT IN MY FRIENDS HOUSE & THEY HAD NO IDEA…” and “EATING ONLY ONE COLORED FOOD FOR 24 HOURS!” The videos are high energy, colorful and frantically edited, appealing to youngsters with short attention spans. That makes her posts feel strangely authentic, like a teenager really could have produced them.

“I started just basically posting content that I felt reflected me, because I wanted my audience to know Jenna for Jenna,” she says. “There’s always an actor side that feels untouchable, or like you can’t know that person, and I wanted to make sure that people could watch me and feel like they know me.”

Miss Wannabe

It could be why her single “Miss Wannabe,” which she calls her “most savage song yet,” has drawn comparisons to “Before He Cheats” by Carrie Underwood, the quintessential female rage country song. It has blown up on TikTok, where authenticity is a social currency that can’t be bought, as other creators shared the song with their own breakup stories.

“Well, she's a bottle of beer and I'm a glass of champagne / She's a fake veneer and I'm the real dang thing,” she sings cheekily, dismissing her ex’s new partner as a cheap imitation. Later, she continues: “He's kissing her, but he's missing me / I pity pretty little miss wannabe.” It is pretty savage.

It’s no coincidence that Davis is experiencing concurrent career highs. But, she insists, she’s not capitalizing on recent viral success to propel her musical success; she’s always been a singer (look no further than the awkward pre-teen videos that live on the internet forever).

“I don’t know if I would go as far as to say it’s insulting, but I think it’s just not true,” she says of the implication. “[Having] a social media presence, everyone’s going to have opinions, and that’s OK.”

She clearly has her own opinions too, and as she matures, her lyrics have as well. “When I was younger… well, I was a child, so I didn’t really have much to say,” Davis says. “I don’t think that as a little homeschooled girl, I had a lot of life experience … Now, I’ve gotten older and lived a bit longer and know what I want to say as an artist.”

Her mom got her obsessed with country legends at a young age. Even after they moved from Texas to Los Angeles, Dolly Parton, Shania Twain and Patsy Cline were on repeat. She’s also related to Gene Autry, a country music icon known for “Home on the Range” and “Back in the Saddle Again,” whose career began in the 1930s.

“I love the storytelling of country music, and I think a lot of people have a phase when they’re growing up and around country music so much that they turn from it,” she says. “I was always just like, ‘Give me more!’”

Finding her voice

Her upbringing may have helped mold her voice as a country singer, but the voice of a homicidal android that gave her her breakout acting role in M3GAN came to her while she was on the floor of her bedroom closet.

That’s where she auditioned for the gig, and given the odd circumstances, she was shocked to book the role — and thrilled when the movie became a surprise box office hit in 2023.

Davis voices a doll powered by AI that goes on a murderous rampage. (Amie Donald plays the other half of the role, portraying her physically onscreen.) In the sequel, she’s back with a different mission: Stopping another doll like her who has gone rogue and become a military-grade weapon. She’s still pretty evil, but she’s hellbent on protecting her young owner, Cady, at all costs.

Davis has a lot of love for M3gan. As she told the news outlet PRIDE, she hopes that the character might become a horror legend like Chucky.

“I think it was the most unexpected surprise, but also a thrill, but also nerve-racking at the same time, introducing a new villain into such an empire,” Davis says of initially booking the role, gushing about the impact that production company Blumhouse has had on horror. It had a hand in bringing iconic films like Paranormal Activity, The Purge, Get Out and now M3GAN to life.

As the heroine of so much of her songwriting, playing a villain was new for Davis. She says it’s “challenging and uncanny, but at the same time, M3gan is a lot more than a villain.”

“She is very sassy and witty and fun, and just has so much spunk and spite and sass. It’s very fun to play her because she has so many levels,” Davis tells Yahoo.

As someone with a lot of levels herself — after all, she’s a singer, an actress and a social media savant — Davis gets it. She doesn’t have M3gan’s penchant for violence, of course, but she’s known to be lyrically savage.
