Rosie Huntington-Whiteley has backed out of hosting "Project Runway: All Stars" not that filming for her new movie "Mad Max: Fury Road" has begun.

Rosie Huntington-Whiteley's recent decision to back out of the job of hosting this year's "Project Runway" due to the start of filming for "Mad Max: Fury Road." The unexpected departure have sent producers of the show on a desperate replacement  finding spree. They've auditioned quite a few people including the likes of Karolina Kurkova, Hilary Rhoda, Elaine Irwin, and Rachel Roy. They've settled on model Carolyn Murphy to replace Whiteley.

Huntington-Whiteley herself was a replacement for Angela Lindvall, who had previously hosted the show. However, earlier this year Lindvall left the show without an explanation.

A friend of Huntington-Whiteley's insists she was "never fully committed to the project and there was no signed contract." While the actress has left the position of host for the show, rumors have it that she will return as the guest judge. A source from the show said her sudden decision not to host the show caused a big fuss.

"Literally days before filming, the show suddenly had no host," the source said. "Rosie had been pushing really hard for the job. She'd charmed everyone. But then with less than three weeks to go, Rosie pulled out to do Mad Max, creating a huge drama. It put the production in a terrible position, and the Weinstein Co. even threatened to sue Rosie."
