Chris Brown was so paranoid about keeping his attendance at Rihanna’s birthday party a secret, he actually tried to force attendees to sign confidentiality agreements
Chris refused to enter the private party Monday night at the famous Hearst Mansion in Beverly Hills until everyone signed an NDA. Though they didn’t get everyone to sign it, Chris eventually walked in and spent most of the night next to Rihanna.
According to sources, Chris and Rihanna sat next to each other, talking and holding hands.
Other celebs in attendance were Katy Perry, Bruno Mars, and Chris Martin.
