Shamed R&B singer Chris Brown has lashed out at music retailers who are refusing to stock his latest album following his conviction for attacking ex-girlfriend Rihanna.

The “Kiss Kiss” hitmaker has kept a low profile since the assault in February, for which he was sentenced to six months hard labour and five years’ probation in July.

But despite several public apologies over the incident, the controversy surrounding Brown refuses to go away – he insists several major stores are “blackballing” his comeback record Graffiti, which was released on Tuesday.

On his Twitter.com page, Brown rants, “I’m tired of this s–t. Major stores r (are) blackballing my cd. Not stocking the shelves and lying to costumers. What the f–k do I gotta do…”

He adds, “WTF… yeah I said it and I ain’t retracting s–t. I’m not biting my tongue about s–t else… the industry can kiss my a–.”

It is not known which retailers are reportedly refusing to sell the album.
