It was November 2023 when I first met Ana Castela. She was backstage at Caldas Country, the festival in Caldas Novas in the Brazilian state of Goiás. At the time, she avoided speaking to the press before her show and seemed serious and shy as she prepared to take the stage. It was only her second time at the festival — just over a year had passed since her name first appeared in the media thanks to her song “Pipoco,” a collaboration with Melody and DJ Chris no Beat. Yet she was one of the main attractions of the night.

Nine months passed before I met Castela for the second time. This time, though still a bit shy, she was at one of the world’s biggest music festivals — Rock in Rio — to join duo Chitãozinho and Xororó for the “Brazil Day” celebration, the first in the event’s 40-year history. “For me, it was an honor. I consider them my grandparents,” she joked in her dressing room at Cidade do Rock, embraced by the sertanejo duo. Castela still seemed nervous about her upcoming performance, but she projected a new confidence, amplified once she took the stage. She faced a crowd singing along to her hits (“Nosso Quadro,” “Solteiro Forçado” and “Sinônimos”), including children of all ages wearing headbands with her nickname, “Boiadeira.”

Born in Amambai, Mato Grosso do Sul, Ana Castela certainly couldn’t have imagined the success she would achieve by embracing the “boiadeira” style. Dressed in a cowboy hat, boots and a wide belt (much as an American cowgirl might), her so-called “agronejo” music blends sertanejo (Brazilian country music) and Brazilian funk, with lyrics about the agribusiness lifestyle. She is now one of the most listened-to artists in Brazil — a title she’s consistently held throughout 2024 — who as of this writing had two songs on the Billboard Brasil Hot 100 and spent 31 consecutive weeks at No. 1 on the Artists 25 Brazilian chart.

She entered the music scene at 17 but is still, at 21, trying to absorb the whirlwind of her life. “It was a drastic change, to be honest,” she says. “Before, I had a completely anonymous life. Now, people want to know everything about me, follow me around. It’s changed a lot.” Speaking to Billboard Brasil, she is still very much the girl from a countryside farm, pausing occasionally as if she is still trying to reconcile who she was and who she is today: “I’m enjoying the fruits that fame and the world are giving me, but always with caution.”

She’s followed by over 27 million people on social media, where she offers fun looks at her personal life — a Disney vacation, cute videos with her boyfriend, the singer Gustavo Mioto — and she’s starred in various commercials and advertising campaigns. “Ô loco [Wow],” she marvels. “Doors just keep opening for me. I never thought my face would be on a shoebox. It doesn’t just help my career; it makes dreams come true that I never even imagined. It’s awesome.”

But her feelings around her wildly increased presence are also conflicted. “My life is no longer mine. I don’t have a private life anymore; everyone knows everything I do,” she laments, though she adds that she’s getting used to it. When I ask if she’s receiving any professional support, Castela says that she started therapy about a month ago: “I think no mind is strong enough to go without a professional for so long.”

She knows the truth of that firsthand. At a performance at the Festa do Peão de Barretos in 2023, one of the most important sertanejo festivals in the country, she broke down while preparing to sing “Solteiro Forçado,” one of her breakthrough hits. “Sorry I can’t sing,” she sobbed in front of a massive crowd. “I swear I’m studying and working with a vocal coach to improve. It’s exhausting as hell, but I’m giving it my all.” Backstage, it was equally tough. “I was in a bad headspace,” she recalls.

Excessive work, plus the overwhelming experience of her fame, had taken a toll on her emotionally. “I couldn’t hit the note that day — I was so insecure,” she says. Criticism from both the public and within herself fueled her drive to improve. “You need to evolve. I was born with the gift of singing, but I need to perfect it.”

Therapy, her Christian faith and her family — an unconditional support system — now help her cope. She also strives to balance the needs of Ana Flávia (her real first name) and Ana Castela. In her free time, she enjoys hanging out with friends at her farm in Londrina, Paraná, and visiting São Paulo for shopping. “Those are the days I can just be young,” she jokes, as if on others she must be a more mature version of herself.

Her latest project, Herança Boiadeira, released in September 2024, embodies this balance. Recorded at her farm, it features collaborations with iconic sertanejo artists like Matogrosso & Mathias, Eduardo Costa, Paula Fernandes and Gino & Geno. “I wanted it to be mine — not Ana Castela’s, but Ana Flávia’s. A tribute to my roots, my upbringing on the farm. My grandfather loved these artists, and so did I,” she explains. In fact, one standout track features her paternal grandparents: “Minha Herança,” with its heartfelt lyrics reflecting a longing for lost time.

Next year, Castela will step into the shoes of iconic artists before her when she becomes the ambassador of the 70th Festa do Peão de Barretos, where she quickly has risen from playing a secondary stage in 2022 to the main stage in 2023 and again in 2024. Pedro Muzeti, artistic director of the festival, says Castela’s evolution represents the future of sertanejo music: “It’s a renewal of the rodeo audience. Having someone young represent such a historic event is fitting.”

Her appeal to younger fans is certainly evident in the kids who wear her signature hats (“They’re adorable; I love them,” Castela says), and she’s launching Turma da Boiadeirinha, a YouTube channel featuring kids songs. But her future, she realizes, very much revolves around an adult audience. She’s collaborated with big names like Gusttavo Lima and Luan Santana and dreams of pairing up with Luísa Sonza and Anitta. And after winning best sertanejo album at the 2024 Latin Grammy Awards, Castela has her sights set on an international audience next.

“If it works, I’ll go for it,” she says. In 2025, she plans to incorporate pop into her shows but stay true to her roots: “I’ll always bring my hat wherever I go,” she insists. “It’s important to show the strength of our music on the global stage.”
