Lionel Richie used to call Michael Jackson "smelly" because the late King of Pop rarely changed his clothes.
The veteran singer was close friends with the late King of Pop prior to his death in 2009 - co-writing their 1985 song We Are the World and making him godfather to his daughter Nicole Richie - and he's now revealed the singer had questionable hygiene habits so he and producer Quincy Jones came up with an unflattering nickname for him.
