Julia Michaels burst onto the scene in 2017 with her super-relatable insecurities anthem “Issues.”


The breakout track earned the nascent pop star two “Big Four” nominations at the 60th annual Grammy Awards: best new artist and song of the year. But long before Michaels, 24, became a household name, she was Top 40’s secret songwriting weapon.


The Iowa-born, SoCal-bred sonic wunderkind began writing music as a teen. And by 2013, her knack for relatable lyrics and earworm hooks earned Michaels her first hit, Fifth Harmony‘s “Miss Movin’ On.” To date, she’s crafted 16 Hot 100 singles for other artists, many of which she cowrote with her songwriting “husband” Justin Tranter.


“Sometimes an artist will come in with an idea or a concept or something and we’ll help them figure it all out, or sometimes they’ll just talk and we’ll hear something that they say and are like, ‘Ah, that would make a great song!’ and we’ll just kinda mold the song around our conversation,” Michaels says of her A-list collaborators, which include Demi Lovato and Pink. “It all depends on who we’re with that day.”
