Calvin Harris says Chris Brown 'stole' his song

Calvin Harris says Chris Brown 'stole' his 2009 number 1 single I'm Not Alone

Calvin Harris has launched a twitter rant accusing R&B star, Chris Brown, of "stealing" his number one single I'm Not Alone.

He posted a link to a YouTube version of Rihanna's ex's new single, Yeah 3x.

The Flashback singer tweeted: "Choked on my cornflakes when I heard new Chris Brown single this morning" last Tuesday (28 September).

He also tweeted that he was receiving a number of abusive messages from Chris Brown fans after making the comment.

The DJ told fans: "I don't care that you call me a nobody. Stealing is still stealing, doesn't matter who you are!

"Because Chris Brown is an international celebrity doesn't make it OK to rip off a guy from UK not many people have heard of."

The 26-year-old also tweeted that Brown's new track sounded "just like" his single from last summer.

He said: "Of course I'm not going to take it to court. What good would that do?! Happy for people to make their own mind up."

The DJ bowed out of the argument between himself and Brown's fans by re-posting the links to his single and Yeah 3x.
