Singer Chris Brown has apologized to pianist Robert Glasper, whom he insulted after the latter beat him for Best R&B Album at the 65th Annual Grammy Awards.

The 33-year-old singer took to Instagram Stories Monday to share a screenshot of the direct message he sent to Glasper, who bagged the award for his album "Black Radio III."

"Congratulations my brother," Brown said, as per the screenshot. "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."

He went on to blame the Grammys for including both of them in the same category.

"THE ORGANIZATION ISNT DOING US BLACKS OUR DUE DILIGENCE. YOU AND I SHOULD never be in the same category," Brown continued. "Two totally different vibes and genres. So from one black man to another.. CONGRATULATIONS.. HOPE YOU ARE ABLE TO FEED YOUR FAMILY FOR LIFE. God bless my G."

A screenshot of Brown's Instagram Story has since made rounds on Twitter.

The apology came after Brown came up with a series of Instagram Stories in which he mocked Glasper and his Grammy win.

"YALL PLAYING WHO DA F-CK IS THIS?" Brown wrote as he shared a screenshot of the announcement saying Glasper won the award.

In another Instagram Story, Brown noted, "IM GOING TO KEEP KICKING A-- RESPECTFULLY," before adding one more Instagram Story, in which he said, "BRO WHO THE F-CK IS ROBERT GLASPER?"

Glasper has not made any social media posts regarding Brown's tantrum or apology.

The 44-year-old pianist won the Best R&B Album award at this year's Grammy Awards, beating Brown who was nominated for his tenth studio album "Breezy." The other nominees in the same category were Lucky Daye for "Candy Drip," Mary J. Blige for "Good Morning Gorgeous" and PJ Morton for "Watch the Sun."

Brown has been nominated at the awards show 21 times over the years and won only once for his 2011 music album " F.A.M.E." Glasper, on the other hand, has been nominated 12 times and won five times so far.

The 65th Annual Grammy Awards was held at Arena in Los Angeles, California, Sunday night. Hosted by comedian and talk show host Trevor Noah, the show was broadcast on the CBS network and streamed live on Paramount+.
