The 61st annual Grammy Awards went down last night, and it was eventful, to say the least. Michelle Obama dropped by for a surprise appearance at the beginning which had many people in the audience (and watching at home) completely shook. Childish Gambino, despite not attending the show, won both Record and Song of the Year for "This Is America," the first ever rap song to win either of those awards. Ariana Grande also stayed home but won Pop Album of the Year for Sweetener, her first Grammy.

Janelle Monáe, despite not winning either of the two awards she was nominated for, absolutely electrified the stage, and people took notice. The best reaction to Cardi B's Rap Album of the Year win for Invasion of Privacy was probably Cardi herself, but of course countless others were ecstatic for her.
