"The Warning" is a hip-hop diss song written and performed by American rapper Eminem and produced by Dr. Dre as part of an ongoing conflict with singer Mariah Carey. Throughout his career, Eminem has claimed he once had a relationship with Carey, dating her for six months. Carey, however, always denied the claim. As a result, Eminem recorded a number of songs in which he rapped about the singer in a negative light, angered by her not admitting to seeing him.
