Rihanna's nude photos: Update

A few days ago, nude photographs of Rihanna hit the web.

48 hours later, the 21-year-old refused to release a public statement, but her record label, Island Def Jam Music Group, sent a letter to at least one website that published the photos.

The letter refers to "unauthorized photos purported to be...Rihanna," and demands that the photos be removed from the site, and calls the photos a violation of "the Artist's rights." They neglected to confirm whether or not the photos were of Rihanna, however.

Chris Brown's reps were quick to release a statement to Essence.com saying, "This is both a false and defamatory statement. Chris has not released or 'leaked' any photos of Rihanna (or anyone else for that matter)."

However, one of the original photos that leaked was of Brown sitting on a hotel bed with pink panties on his head. Another photo with Rihanna in bikini bottoms and a white dress shirt (above) has "I love you - Robyn. I miss you." scrawled across the bathroom mirror.

If Brown didn't leak them, then who did?

When will these celebrities ever learn??
