Lady Gaga has apparently threatened to sue the makers of ice cream - titled Baby Gaga - made from human breast milk.

Lawyers representing the 24-year-old singer have sent a letter to the Icecreamists shop in London, accusing the store of riding on the coattails of Lady Gaga's trademarks in a manner that is deliberately provocative and, to many people, nausea-inducing.

The references you are making to Lady Gaga are thus clearly deliberate and intended to take advantage of her reputation and good will... Associating the Lady Gaga mark with a food product which may be unsafe for human consumption is also highly detrimental, the letter adds.

The lawyers have given the ice-cream maker until Wednesday to change the name if you wish to avoid proceedings for trade mark infringement and passing off, reports Britain's Evening Standard.

O'Connor shot back, calling the legal threat outrageous and unnecessary. For Lady GaGa to accuse us of stealing her image is laughable when you consider how much she has borrowed from popular culture to create her look and music, O'Connor said. Since the dawn of time the word 'gaga' has been one of the first discernible phrases to come from a baby's mouth. This is why we chose the name.

As for her assertion that our product is distasteful, perhaps she should reflect on her blood-spurting performance at the Mtv Video Music Awards, or the fact she wears clothes fabricated from the flesh of dead animals. We have applied to register the trademark Baby Gaga and are confident we'll secure this, he said.

We think this is very unnecessary, the whole thing will be over by next week, but we are prepared to fight this in court... This is a David versus Goliath battle I'm convinced we will eventually win, O'Connor was quoted as saying to Britain's Evening Standard.

Last week, local officials on the Westminster City Council decided to confiscate the ice cream after two complaints were filed over whether a shop should be selling edibles made from other people's bodily fluids.

There is some concern that several dangerous viruses, contaminants and diseases can be contracted through breastmilk.

The new recipe blends the breast milk with Madagascan vanilla pods and lemon zest, which is then freshly churned into ice cream. The Icecreamists started selling the new flavor, priced at 14 pounds ($23), on Feb. 25. The first batch of the ice cream was sold out within days of its introduction.
