Supermodel Naomi Campbell has blasted reports she is planning an elephant polo match to celebrate her boyfriend's 50th birthday, insisting she is devastated by the "completely untrue" allegation.

The British beauty attracted criticism from officials at People for the Ethical Treatment of Animals last week after a report surfaced suggesting she had organized the animal-based event in India for Russian billionaire Vladislav Doronin's party.

However, she has now hit back, branding the speculation false and insisting no elephant polo will be taking place at the celebration.

In a statement, a spokeswoman writes, "An allegation has been made in the media that Naomi Campbell is responsible for organizing an elephant polo tournament for her partner Vladislav Doronin's 50th birthday celebrations in India. Also, that Miss Campbell has no concern over the potential cruelty to elephants involved in such polo tournaments.

"These allegations are completely untrue. Miss Campbell has neither organized nor requested the organization of any such elephant polo tournament as part of the birthday celebrations or otherwise.

"Miss Campbell is extremely upset by these untrue allegations, which were first published in a U.K. newspaper and which have been widely repeated around the world, and has instructed her lawyers in London to deal with the matter immediately."
