Mamadee grew up with her parents, two sisters, and her grandparents in a small village called Altrottmannsdorf,[1] near Zwickau as the youngest daughter of a father from Sierra Leone and a German mother.

Her song Good Days, which she wrote and performed with the American singer Tamika, appears also on the album Gentleman & The Far East Band Live.

[1] In 2007, director Sven Halfar produced the documentation Yes I Am in which the lives of Mamadee, Adé Bantu and D-Flame were portrayed.

The film shows the career development of Afro-German musical artists and the problems they have encountered due to their skin color.

She tried to come to terms with her own history in her song Farbgesetz which was featured in the Yes I Am documentation and did educational work for youths in schools since she joined in 2000 the non-profit association Sisters e.V.
