Heidi Klum has outdone herself again at her annual Halloween bash last Saturday. Notorious for the best costumes and celeb guest lists, she would never be outshone at her own party.

The Project Runway host, ex Supermodel and yummy mummy failed to disappoint fans as she hinted on social media in the run-up to the event, showing prosthetic artists hard at work reworking her facial features and body.

Now this was no easy task Heidi revealed it took the talented makeup and prosthetic team 9 hours to transfer her into the iconic Jessica Rabbit. The transformation included enormous breasts which could have quite easily passed as a rather large breast enlargement. As well as a bum enhancement to create the perfect hour class shape of the cartoon sex symbol.

Little was left to the imagination with a sweet heart neck line and thigh high slit to the glitzily red dress with matching heals. Heidi took to the red carpet unrecognisable to her former self alongside Supermodel of the moment Gigi Hadid who opted for a simpler costume as she took on the sexy alter ego of Sandy in the 1978 blockbuster Grease.

Although Heidi has had some seriously unique and inventive costumes over the years including Planet of the Apes and a skinless human we must say the 2015 Jessica Rabbit is our favourite and we are pretty sure it is obvious why.
