Chris Brown has apologized to Robert Glasper.

The "Loyal" singer had hit out at Glasper on Sunday after losing out to the pianist for the best R&B album award at the Grammys.

Brown's 10th studio album, "Breezy (Deluxe)," was up for the award, but lost out to Glasper's "Black Radio III."

"Y'all playing. Who da fuck is this?" Brown wrote in a series of since-deleted Instagram stories, according to The Shade Room.

"Who the fuck is Robert Glasper," he continued. "I'ma keep kicking y'all ass respectfully."

Brown also shared an edited photo of himself playing the harmonica, alongside which he quipped: "I gotta get my skills up. Ima start playing the harmonica."

"New Level Unlocked! Harmonica Breezy," he teased.

On Monday, Brown then shared an Instagram story that showed him messaging Glasper to say sorry.

"Congratulations my brother," the message began.

"I would like to apologize if you took offense to my reaction at the Grammys, you were not the intended target and I know I came off really rude and mean. After doing my research I actually think your amazing."

Brown added in his apology that "the organization isn't doing us blacks our due diligence" by putting them in the same category because they are "two totally different vibes and genres."

"From one black man to another, CONGRATULATIONS," he concluded. "HOPE YOU ARE ABLE TO FEED YOUR FAMILY FOR LIFE."

Pianist Glasper, 44, has released 11 studio albums on his own and has written and featured on tracks for Kendrick Lamar, Mac Miller, Common, and Talib Kweli.

As of Sunday, he has been nominated for 11 Grammys and won five.

Brown, 33, has been nominated for 18 Grammys, winning one. His fourth studio album, "F.A.M.E.," took home the award for best R&B album in 2012.

Elsewhere at Sunday's Grammys, it was Beyoncé who stole the show as she became the most-awarded person in Grammys history.

The 41-year-old star collected four awards on the night, including best dance/electronic album for "Renaissance."

It means she has now won a record 32 Grammy Awards during her career — one more than the late classical conductor Sir Georg Solti.

In her acceptance speech for best dance/electronic album, Beyoncé thanked her husband Jay-Z, their three children, her parents, and her late Uncle Jonny, to whom "Renaissance" was dedicated.
