Painest and arranger Robert Glasper won Best R&B album at the Grammys last night
Chris Brown was among the nominees that Glasper's Black Radio III beat out for the award.
Brown did not take it well.
Breezy lashed out at Glasper multiple times on social, constantly questioning who the 44-year-old five-time Grammy winner was.
"Who the f*ck is Robert Glasper," Brown typed.
Brown also claimed he needed to take up the harmonica so he can win awards as Glasper does.
Brown won the Grammy for Best R&B album in 2012 for F.A.M.E. Other than that he's come up empty on music's big night, despite 21 nominations.
