Chris Brown says he has nothing to do with the allegedly leaked Rihanna pictures. (AP file) Rihanna's rep demands photo removal Rihanna in nude photo scandal?

Chris Brown has shot down gossips speculating he leaked naked pictures of Rihanna on the Internet, insisting he had nothing to do with the scandal.

A set of snapshots apparently featuring the Umbrella singer in various states of undress surfaced online on Friday.

Gossip bloggers speculated Brown was responsible for leaking the photos following the couple's February bust-up that left Rihanna battered and bruised.

But the Kiss Kiss hitmaker is adamant he had nothing to do with the photos coming to light.

A representative for the star tells Essence.com, "This is both a false and defamatory statement. Chris has not released or 'leaked' any photos of Rihanna (or anyone else for that matter)."

The on/off couple are currently embroiled in a legal case after Brown was accused of felony assault and making criminal threats.

Earlier this week, lawyers for Brown filed papers at a Los Angeles court asking the city's police department to explain how pictures of an injured Rihanna, taken after the alleged altercation, were leaked on the Internet.
