Lady Gaga has won an injunction that bans songs from Lady Goo Goo, an animated baby character from the popular online children's game Moshi Monsters.
Gaga's injunction, granted at London's High Court earlier this week, will ban the character from promoting, advertising, selling, distributing or otherwise making available to the public The Moshi Dance, the company's firm Mind Candy told BBC News.
Lady Goo Goo and The Moshi Dance first caught the attention of millions around the world when a music video was released on YouTube earlier this summer (the video has since been removed).
According to the BBC, some lyrics of The Moshi Dance include my stroller's pretty and my diapers are silk, I throw my toys out if I don't get milk.
Owners of Moshi Monsters had plans to release the full Lady Goo Goo song on iTunes later this year.
With the new ban, the company is also prohibited from releasing any music or music videos performed by Lady Goo Goo.
The baby character, whose features include sparkly purple sunglasses, blonde hair and a pacifier, also has another Gaga-like song, called Peppyrazzi, a parody of Gaga's 2009 hit single Paparazzi.
It was a strange ruling - we certainly weren't expecting to lose . . . we've had a huge amount of public support. I think this could be a worrying precedent for other parody acts and tribute bands, the company's chief executive Michael Acton Smith told the BBC.
Moshi Monsters, a game targeted at children aged 7 to 12, also has characters called Dustbin Beaver and Roxy. The London-based game company was developed in 2007 and has since attracted as many as 50 million registered players, according to The Daily Telegraph.
Lady Gaga is currently in New York City filming the music video to her upcoming single, Marry the Night, the fifth release from her second studio album, Born This Way.
While the official Moshi Dance video was removed from YouTube, unofficial versions like the one below still exist.
