Female African Musician With Short Hair And Strapless Gowns

There's this black lady musician that's shown regularly on the one of the network ads on DSTV. 

Her music videos have been featured heavily on the Series Channel in the past.  In her music videos she usually smiles a lot and dances on her own, wearing bright-colored strapless gowns and a short haircut, clapping from time to time.

I've seen her videos twice.  Once, she was singing an English song with lots of what I think was "I want to have ___" and the other time, she was singing in a language which I think is an African language.  Both times, she was dressed as I described.

I would like to know her name.  Thanks!  They currently show a second of her on a DSTV network ad.
