Holly Willoughby Halloween costume: TV presenter channels Morticia Addams and looks 'stunning' with black wig

Holly Willoughby traded her blonde locks for a black wig in a bid to transform herself for Halloween.

The This Morning presenter unveiled her costume for this year’s Celebrity Juice special giving her four million followers a shock on Wednesday.

Taking to Instagram, the 37-year-old posed in a PVC black leather-look bodycon dress.

She tied the look together with the black wig, frosty white skin, dark smoky eye makeup and bold red lips.

She captioned the post: “Well it’s Halloween again on @celebjuiceofficial ... Morticia is out to play ... thank you @mrwilliamwildefor the most perfect dress! Ring by @vickisarge shoes @ginashoesofficial ... @patsyoneillmakeup and @angiesmithstudio you’re the BEST!”

Stunned fans flocked to the mother-of-three’s comments to praise her for the “amazing” look.

One user wrote: “Wow look amazingly hot.”

Another commented: “Your figure in this you look like Jessica Rabbit x”

A third added: “Super super sexy! You look amazing!! Xxx”

Meanwhile, a fourth posted: “Wow stunning look.”

Willoughby later shared another snap alongside singer Danny Jones and TV chef Gino D’Acampo, who each donned their own creepy looks.

She captioned the post: “My spooky team... @dannyjonesofficial @theginodacampo.”

On Thursday, the TV star is set to make her final appearance on This Morning for several weeks whilst she joins Declan Donnelly in presenting I’m A Celebrity… Get Me Out of Here.

Earlier this week, it was confirmed that Rochelle Humes has been confirmed to replace Willoughby during her stint away.
