Star magazine is reporting that Mischa Barton is furious with Nicole Richie.
Mischa is creating a new line of high-end headbands and she is very angry that Nicole's House of Harlow 1960 collection also includes headbands.
The designs were similar and Mischa’s line was put on hold.
Star Magazine has a mole, who says: "Mischa is furious. She feels like Nicole completely copied her idea."
