Fifth Harmony's Harmonizers win Best Fan Army at iHeartRadio Music Awards

Fifth Harmony has plenty of reason to celebrate!

The girl group accepted the Best Fan Army Award on Sunday at the iHeartRadio Music Awards on behalf of their dedicated follower the Harmonizers. The Fan Army clocked in 39 million votes in order to secure the group the big win at the iHearts.

The girls were definitely thankful! Ally Brooke, Normani Kordei, Dinah Jane, Lauren Jauregui, took to Twitter to thank their fans for their continued support throughout what has been a pretty difficult past 6 months. Late last year, Camila Cabello, an original member of the group left after nearly 5 years with them.

Fifth Harmony was formed on the "X Factor" after all five women tried out for the show as individual artists and Simon Cowell put them together to form one of the most successful female groups of the past decade.

Congrats to the Harmonizers.
