Pop star Lady Gaga has won an injunction stopping the makers of an online children's game from promoting an animated character called Lady Goo Goo.
British company Mind Candy is behind the Moshi Monsters site, which allows children to adopt a virtual pet monster.
Its characters include Lady Goo Goo, a sunglasses-wearing blonde baby who appears in The Moshi Dance, a video that became an online hit after it was posted on YouTube.
The company had planned to release the song as a single, but this week's British high court ruling bars it from "promoting, advertising, selling, distributing or otherwise making available to the public" any work involving Lady Goo Goo.
Mind Candy founder Michael Acton Smith said Friday that the ruling was "a huge disappointment."
