Model Kate Upton attends the Fashion Group International's 30th annual 'Night Of Stars' awards gala at Cipriani's Wall Street on October 22, 2013, in New York.

London - Kate Upton has reportedly threatened to sue a website after it allegedly posted fake pictures of her naked.

The 21-year-old model is taking legal action against a joke company, Celeb Jihad, after it allegedly edited topless images of the blonde

beauty from her Sports Illustrated magazine shoot with the headline, "Kate Upton Naked Outtake From SI Swimsuit 2014".

Kate's legal team immediately sent the website a letter threatening to sue if it didn't remove the fake snapshots straight away.

According to, Kate's lawyers were not only concerned about the photos containing the star's breasts, but they also claimed in the letter that the pictures had been airbrushed.

Celeb Jihad has since removed the images, which it reportedly branded "boring" and "horrible", from its website.

This isn't the first time the company has come under fire for editing photographs after it allegedly published a snap of a topless, blonde, woman, which it claimed was Taylor Swift in 2011.

The 24-year-old singer's legal team reportedly threatened to sue for wrong identification and for trademark infringement.

However, the picture was taken down immediately. - Bang Showbiz
