I whanau a Bieber i te Poutu-te-rangi 1, 1994, i Rānana, Ontario, i te Whare Hauora o St Joseph, i whakaarahia i Stratford, Ontario. Ko ia te tamaiti anake a Jeremy Jack Bieber me Patricia "Pattie" Mallette, kaore i marenatia. Ko Mallette he tamariki iti i te wa i whanau ai ia, a ko tana whaea a Diane me te papa-papa Bruce i awhina i a ia ki te whakatipu i tana tama.
