A group of U.K. campaigners want music fans to think before they purchase Chris Brown's fifth studio album "Fortune."

The campaigners placed cautionary labels that read, "WARNING. DO NOT BUY THIS ALBUM! THIS MAN BEATS WOMEN," on a handful or so of Brown's "Fortune" albums at, at least, one London HMV megastore, reported E! News

The labels made reference to Brown's brutal assault on Rihanna in 2009. 

It is still unclear as to how wide spread the campaign was, E! News reported.

A group of anti-domestic violence campaigners are allegedly behind the warning labels, though no one has claimed responsibility yet. 

Brown's rep has not yet commented on the incident; however, HMV has. 

"It was very much an isolated incident and nothing to do with HMV or representing our views," a spokesman for the store told E! News. "It would appear a member of the public popped into one of our stores yesterday and stickered a handful of CDs.

"These were spotted and quickly removed, but, before we could act, the individual concerned must have taken a photo and sent it to the media. To our knowledge there are no further stickers in our stores now."

The R&B singer's violent past has recently made headlines. 

Brown recently got a black-and-white tattoo on his neck, which seems to depict a woman's partially disfigured face.

Many are comparing the image to the 2009 picture of Rihanna's bruised and lacerated face that was taken after the infamous incident. 

However, Brown's rep told Gossip Cop that the tattoo ""is not Rihanna."
