Robert Edward Davis (born 28 December 1979), better known by his stage name B-Tight, is an American-born German rapper.

Davis was born in Palm Springs, California, to a German mother and an African American father, but grew up in Berlin.

Davis grew up in Märkisches Viertel in Berlin, where he also met his later roommate and rap partner Sido, with whom he formed the duo A.i.d.S and they began to write song lyrics.

B-Tight released his EP Der Neger (in mir), in 2002, but it caused controversies as its hard and aggressive song lyrics, which were typical of the label's music style.

B-Tight is affiliated with the music label Aggro Berlin with whom he released a number of hit singles; amongst them, "Der Neger".
