Chris Brown Didn't Want To Be Seen At Rihanna's Party..

Chris Brown made news once again when he refused to enter the Hearst Mansion in Beverly Hills, where Rihanna's Birthday party was held, until all of the guests signed a confidentiality agreement.

The two were later seen spending most of their time together. This all after the restraining order was lifted.

Amongst some of the stars attending we're Katy Perry, Bruno Mars and Chris Martin. Rihanna's cake was in the form of a Huge Joint.. Pretty Awesome if you ask me..!!
