'American Idol' winner says husband 'put his badge up' to support her music career

Country singer Hannah Harper, who emerged victorious in the 24th season of "American Idol" in 2026, has experienced a rapid transformation in her professional and personal life. Central to her journey is the profound decision by her husband, Devon Mendenhall, to leave behind nearly a decade in law enforcement to fully invest in her burgeoning music career.

Mendenhall, after serving eight years as a police officer, initially transitioned into an insurance role. However, as Harper’s schedule intensified following her win, the couple sought a sustainable way to manage the demands of her rising profile without fracturing their family unit. Ultimately, Devon embraced the role of tour manager, integrating himself into the daily grind of life on the road alongside his wife.

This career pivot has not only allowed Harper to pursue her country music aspirations but has also reinforced their marital partnership. The couple, married since April 2018, balances their professional collaboration with raising three young boys, creating a close-knit family presence throughout Harper’s first national tour.

Harper’s ascent in the country music scene has been marked by milestones beyond her "American Idol" victory. Notably, her original track "String Cheese" resonated widely, going viral during the competition and capturing the attention of major brands. This success led to a sponsorship deal with Sargento, which includes a custom tour bus stocked with the company’s products, underscoring the commercial momentum accompanying her artistic breakthrough.

While working closely with her husband has brought numerous rewards, Harper acknowledges the challenges inherent in blending their professional and personal lives. Establishing boundaries between work hours and family time remains a work in progress as they navigate the unique demands of touring and managing a music career together.

The shared commitment of Harper’s family extends beyond her husband. Her parents and brothers also accompany her on tour, each contributing to the collective endeavor. This familial involvement creates a support system that Harper regards as integral to her ongoing success and well-being on the road.

Harper’s music has also struck a deeply emotional chord with her audience, particularly with "String Cheese," a song inspired by her experiences with motherhood and postpartum depression. This track has evolved into an anthem for many parents facing similar struggles, fostering a meaningful connection between the artist and her listeners.

In navigating the complexities of newfound fame, Harper has looked to established artists for guidance. Advice from fellow "American Idol" alumna Carrie Underwood has helped her differentiate between her performance persona and her authentic self, a balance that is crucial for maintaining her identity amid public scrutiny.

Though details about Harper’s future projects remain limited, she continues to tour nationally through November, sharing stages with notable acts such as Brad Paisley and Lauren Alaina. The combination of professional growth, family solidarity, and artistic authenticity positions Hannah Harper as a distinctive figure in contemporary country music.
