Kim Kardashian Hollywood Game
Kim Kardashian: Hollywood iPhone and iPad game has 30 million active users iTunes

Kris Jenner is being sued by video game developers Kung Fu Factory, who claims she stole ideas for the Kim Kardashian: Hollywood app. TMZ reports the momager is facing a legal battle with the company, who says Jenner and her agent were in talks with them in 2011 before using their concept to create their own format two years later.

According to the suit, Kung Fu says it came up with the format and presented a proposal – which included everything from how Kardashian and her sisters Khloe and Kourtney's characters would look to how the game would be played.

In 2013, Kim teamed up with Glu Mobile, a company known for creating games for smartphone and tablet devices, to help launch her animated alter ego the following year. The app, which sees fans navigate their way around Hollywood with the Keeping Up With The Kardashians star, currently has 30 million active users.

Kardashian recently credited her rapper husband Kanye West for decision to venture into the world of gaming. "Kanye really talked me into doing this partnership. He always wanted to do music for video games, so he thought it was the coolest thing in the world to have a video game with a character of myself," she told Mail Online in June.

"And as long as I had some control over the look of the character, what the character would be wearing and saying and doing, it would be so much fun, and it proved to be so right. I thank Kanye every day for making me do this deal."

In their lawsuit, Kung Fu Factory demands damages and profits from the game – which made $200m (£131m) in its first year.
