Yaa Yaa started her career as Bertha, auditioning for ‘Stars of the Future’ in 2009 with Whitney Houston’s song, ‘Greatest Love of All’. She and her brother, Kankam, after they both auditioned in Kumasi, Ghana, made it to the semi-finals. Yaa Yaa was picked as one of the final 12, but unfortunately her brother was unable to contest further in the competition. She went on to win the competition.[4] Yaa Yaa considers the win the starting point of her career. One of her prizes of winning ‘Stars of the Future’ was the privilege of being an MTN Ambassador for one year. Her tenure with them was successful and MTN continued to renew her contract consecutively for the next two years following her win.[5] As organizers of the reality television show, Charter House managed Yaa Yaa for two years.
