Singer/rapper Chris Brown is reportedly facing problem in finding a suitable venue to celebrate his 21st birthday.

According to sources, Brown has been looking for places like clubs in New York, Miami and Las Vegas.

However, all venue holders and promoters are apparently afraid to book their place for the singer, as they don’t want to spoil their ‘potential’ relationship with Brown’s ex-girlfriend Rihanna.

“They don”t want to mess up their relationship, or their potential relationship, with Rihanna,” the New York Post quoted a source as saying.

Brown is now said to be looking for private homes or restaurants in Manhattan.
