Chris Brown can`t find venue for birthday

London: Rapper Chris Brown has not been able to find any club willing to hold his 21st birthday party because venue managers are worried about ruining any potential relationship with his ex-girlfriend Rihanna.

The "With you" singer, who reaches the age May 5, is having difficulty getting a club in New York, Las Vegas or Miami to host his bash because they don`t want to upset his ex-girlfriend Rihanna - who he assaulted in February 2009, reports contactmusic.com. "They don`t want to mess up their relationship, or their potential relationship with Rihann," said a source. As a result of the difficulties Brown is now looking to hold the party at a private home.
