Dinah Jane Hansen is the youngest member of girl group Fifth Harmony, which was formed on the second season of the TV show The X Factor. In 2018, she and the band parted ways to pursue their solo careers.

​

Her audition song for The X Factor was Beyonce's "If I Were a Boy." She was complimented by L.A. Reid for her vocal interpretation of the pop hit.

​

She, along with Fifth Harmony, signed a joint record deal with Syco Music, Simon Cowell's label, and Epic Records, L.A. Reid's label, in early 2013.
