DC Entertainment has blocked Rihanna from trademarking her first name.

The company, which owns the rights to the 'Batman' series, is trying to stop the 'Rude Boy' hitmaker - who was born Robyn Rihanna Fenty - claiming the rights to the moniker as they believe it's too similar to their legendary comic book Robin, Batman's sidekick.

According to a complaint filed in the US Patent and Trademark Office last week, DC have argued that the names are ''virtually identical'' and believe ''consumers are likely to be deceived'' if she trademarks the name.

The company - which is part of Warner Brothers - added Rihanna's use of the superhero sidekick's name could tarnish his reputation.

The complaint continues: ''(Rihanna's) registration is likely to cause dilution by blurring and tarnishing the famous opposer's mark.''

According to Billboard, the 27-year-old star wanted to patent the name with the aim of launching an online magazine when she filed the request back in June 2014, but DC, who published their own Robin comic book in 1990, believe it will cause confusion''.

They said: ''(A publication called Robyn) is likely to cause confusion, cause mistake, or to deceive the public.''

Boy Wonder Robin first made his first appearance in a DC comic book issue in 1940.
