What is the surname of the singer Usher?

Usher Raymond IV (born October 14, 1978) is an American singer, songwriter, dancer, and actor. Born in Dallas, Texas but raised and lived in Chattanooga, Tennessee until moving to Atlanta, Georgia. He rose to fame in the late 1990s with the release of his sophomore album My Way (1997), which spawned his first U.S. Billboard Hot 100 number-one single, "Nice & Slow".

Usher was born in Dallas, Texas, the son of Jonetta Patton (née O'Neal), from Tennessee, and Usher Raymond III. Usher spent the majority of his young life in Chattanooga: his father left the family when Usher was a year old. Usher grew up with his mother, then-stepfather, and half-brother, James Lackey (born 1984). Directed by his mother, Usher joined the local church youth choir in Chattanooga, when he was nine years old; there, his grandmother discovered his ability to sing, although it was not until Usher joined a singing group that she considered he could sing professionally.
