Justin Bieber's legal team is demanding that media websites who have published naked photos of the star remove them immediately.

The Hollywood Reporter claims to have seen a lawyer's letter sent to the New York Daily News, which originally published the pictures of the star on holiday in French Polynesia.

The photos of the singer in Bora Bora are still live on the US website.

The legal document is demanding action within 12 hours of receipt.

The legal cease and desist letter also acknowledges the photos are of Bieber, despite speculation the photos 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 says the publication of the photos represent a breach of the singer's publicity and privacy rights.

The photos also, according to the letter, infringe Bieber's trademarks.

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