Uh-oh! This can't be good for Kim Kardashian's mental health as the mommy-to-be is busy house-hunting and shopping for shoes with beau Kanye West.

After facing trademark infringement allegations last year for their Khroma Beauty line, the Kardashian sisters have been hit with hefty lawsuit. Celebrity makeup artist Lee Tillett is seeking $10 million in damages from the fashionable trio and Boldface Licensing + Branding, the company that owns Khroma Beauty's license, for allegedly swiping the name of her cosmetics line and adding an "h."

The Orlando Sentinel reports that Tillett, who launched Kroma Makeup in 2004, filed the suit this Wednesday in a Los Angeles federal court. She had previously filed a cease and desist letter back in June to Boldface Licensing + Branding, taking action one step further than Chroma Makeup.

"I developed the Kroma line myself, built my business through my own hard work, and took the legal steps necessary to protect it," Tillett said in a press statement. "And yet I have now been forced into legal battle with the Kardashians simply because they have decided to take something that doesn't belong to them."

While Boldface had told The Huffington Post last October that they too had gone through the necessary legal steps to secure their name, Tillett is preparing to protect her brand's name and money at all costs.
