Fans had a strong adverse reaction to a comment that Chris Brown left on a recent Instagram post by Rihanna.

The “Work” singer posted a photo of her in her underwear to promote her Savage x Fenty holiday lingerie collection. Brown liked the picture and left a flushed-face emoji in the comments, which fans certainly noticed.

“Stay away from Rihanna just stay away,” one user commented. “Leave her alone u psycho,” another wrote, according to E! News.

Of course, fans got particularly due to the two musicians’ dating history together. Back in 2009, Brown was arrested for domestic violence towards Rihanna.

The singer has yet to respond to the comments.
