Rapper Proof, best man at his wedding in January, was blasted in the head in a nightclub row.
Eminem, 33, was later seen leaving his own home in tears.
Proof - Deshaun Holton, 32 - was murdered in a club on Detroit's Eight Mile Road, made famous in Eminem's 2002 movie 8 Mile.
Another man, 35, was shot in the head and was last night critical.
Eminem knew the rapper before becoming a star. It was his friend's idea to form the band D12.
Proof often appeared with him at gigs and also starred in 8 Mile.
Proof's label Interscope Records said: "His friends and family would appreciate privacy during this difficult time."
Last New Year's Eve another of Eminem's hip-hop friends, Obie Trice, was shot and wounded while driving in Detroit.
