TMZ reports Chris Brown was so paranoid about keeping his attendance at Rihanna‘s birthday party a big fat secret — he actually tried to FORCE partygoers 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 — sending his henchmen in beforehand to gather every partygoer’s signature.
According to sources, the two got real intimate, sitting next to each other, talking, and holding hands.. TMZ was also told the party was jam-packed with celebs including Katy Perry, Bruno Mars, and Chris Martin.
Talking about the “Birthday Cake” remix collaboration, Miss Info reports: Rihanna has recorded a remix to her song “Birthday Cake” featuring Chris Brown. Infact recently, the song’s co-producers, Da Internz, hinted to MTV News, that “the feature on [the remix] is gonna shock the world.”
