Karen Mukupa, a singer, musician, and composer, is "in a relationship" with Nikolaj Kirk, a chef and cookbook writer - to quote his Facebook. Karen was born in Zambia, but lived in Tanzania until her teens when she moved to Denmark. There isn't much information on the two of them, and this is the only picture I could find of them together.
