A large family that adore four tall sexy aussi lads from the band 5 seconds of summer. They all share one mother called liz Hemmings aka queen liz or mumma liz. They are the sassiest people you will ever meet. (Mumma liz taught us well). Never get on the wrong side of the 5sos fam it is a place you don't want to be.
