The lovely ladies that are Fifth Harmony have wished 5 Seconds of Summer a happy birthday.
5SOS are lucky guys. What better way to celebrate your third birthday together as a band than having those five babes sing happy birthday to you in well, harmony.
The girls were appearing on a US radio station to promote their UK debut single ‘BO$$’, when they took it upon themselves to pay tribute to the guys three year anniversary as a group, by performing a pop-punk inspired version of the classic happy birthday.
The single is out December 7, the girls will also perform on the X Factor the night of release and the single will feature on their upcoming debut album ‘ Reflection’ which is available in the US January 27.
