Julianne Hough waltzed into America’s hearts as a professional on Dancing With the Stars in the 2000s. In 2008 she donned a cowboy hat and boot-scootin’ boogied into country music with her self-titled debut, which was powered by cuts like the triumphant “My Hallelujah Song” and the playful “That Song In My Head.” She later got the opportunity to flaunt her triple-threat talents in the big-haired jukebox musical Rock of Ages and the throwback fantasia Grease Live! In 2019 she branched into pop with the towering dance-floor anthem “Transform,” an ode to self-love and turning into “me but better than I was before.”
