LONDON: Saucy pics of what appears to be the Umbrella star in a variety of naked poses appeared online last Friday.

However Brown, who split from Rihanna after he allegedly attacker her after a post-Grammys party in February, denies the leak came from him.

Sources in America had accused Brown of releasing the intimate pics in anger after snaps of her battered face appeared online, following the alleged assault.

However a representative for the R'n'B star told Essence.com: "This is both a false and defamatory statement. Chris has not released or 'leaked' any photos of Rihanna or anybody else for that matter."
