Rihanna fans want Chris Brown to stay away from her, even on social media.

Fans of the “Work” singer were none too happy to see the singer’s ex chime in on a photo she posted to Instagram over the weekend of her laying in bed in nothing more than red Savage x Fenty underwear, stockings and a pair of stiletto heels.

Brown, 29, commented with the flushed face emoji, making clear exactly how he felt about seeing 30-year-old in the sultry ensemble.

The Rihanna Navy wasn’t having it, blasting him for even having the nerve to comment on the photo.

“big f–king stupid she doesnt want to hear from you,” wrote one fan.

Rihanna and Brown started dating in 2008 but broke up a year later after he physically attacked her following a Grammy pre-party. Brown pleaded guilty to felony assault and was sentenced to five years of probation.

This isn’t the first time Rihanna’s fans have tried to defend her from her ex on social media. Last year, they went after Brown after he commented on a photo of RiRi in a bejeweled bikini at the Crop Over festival in Barbados.
