Pakistani actress Veena Malik, best known for her participation in Indian reality show Bigg Boss, was at the centre of a fresh controversy today after being featured nude on the cover of 'FHM India' magazine, sporting a tattoo with the words ISI on her arm.

Though Veena, 33, has denied posing nude for the magazine, saying it is a "morphed picture", FHM India editor Kabeer Sharma said the magazine had a video of the photo shoot with her and an email from the actress that proves the authenticity of the photograph.

"I have never posed nude. I have never done anything like that ever. My manager and legal team is looking into the matter. We will take legal action against them," Veena told PTI in Mumbai.

"The picture has been morphed. It's not me. Definitely not," said Veena, who is in Mumbai for reality show Swyamavar.

However, Sharma has a different story.

"The photo shoot was done in Mumbai on November 22. We have a video of the photo shoot," Sharma told PTI.

"I also have an email from Veena in which she says she has seen the photos and is happy with them, and that she's looking forward to seeing the cover," Sharma said.

The cover of the magazine's December issue, posted on FHM India's website, features Malik along with the caption: 'Pakistani WMD Veena Malik on Asif, burqas and work visas'.

The cover has become the topic of discussions and debate in Pakistan, with numerous users of Twitter posting links to the webpage featuring Malik's photograph.

In an apparent reaction to the photo, Pakistani actress Meera, who had earlier called Malik a "cheap girl", posted on Twitter: "Completely mad woman."
