R&B star Rihanna insists a new Instagram.com account set up in her name is a fake.

The Stay hitmaker recently disabled her 'badgalriri' blog after coming under fire from website bosses for breaking their nudity rules by posting risque shots from her sexy covershoot for French men's magazine Lui, in which she was snapped exposing her bare breasts and her nipple piercing.

She was forced to remove the saucy pictures from the photo-sharing site and subsequently decided to close down her page, which had amassed 12 million followers.

However, it appeared Rihanna had returned to Instagram just days later after a profile named 'badgalriri_again' was set up, with a tagline stating, "Im Back B**Ch (sic)!". It also included a Vevo.com link to her video for the song Pour It Up.

News of the phoney page has since been brought to Rihanna's attention and she reached out to her fans via Twitter.com on Monday (19May14) to warn them not to fall for the bogus account.

Alongside a screen grab of the Instagram profile, which had garnered over 47,000 followers, she wrote, "#Phake (sic)!!!! Let’s be clear, I do Not have an Ig account!"
