Los Angeles, Oct 9 (IANS): Singer Justin Bieber's team is cracking down on media outlets which have published nude photographs of him.

According to a cease and desist letter sent to the New York Daily News, which originally published the nude images on Wednesday showing the singer on vacation in Bora Bora, Bieber's legal representatives are demanding the immediate removal of the photographs from its website, reports hollywoodreporter.com.

The letter was sent shortly after the images were published on Wednesday afternoon.

The cease and desist letter also acknowledges that the photographs are, in fact, of Bieber, despite online speculation that the images had been doctored to look like him.

"We recently became informed that your company has obtained and is distributing unauthorised photographs of our client, including images showing him without clothing," reads the letter.

Bieber's legal team states the publication of the photographs represents a violation of the singer's publicity and privacy rights. The images also, according to the letter, infringe on Bieber's trademarks.

The singer's representatives at the Myman Greenspan law firm are threatening to sue if the photographs aren't taken down.
