Ryan Daniel Montgomery, known professionally as Royce da 5'9", is an American rapper. Best known for his association with fellow Detroit rapper Eminem, the two met in 1997 and formed the hip hop duo Bad Meets Evil the following year. Their 2011 single, "Lighters", peaked at number four on the Billboard Hot 100 and preceded the release of their debut extended play (EP), Hell: The Sequel (2011). The song and EP—which debuted atop the Billboard 200—have both yielded Montgomery's furthest commercial success.
