Nicole Kidman gobsmacked over giant Sydney mural: 'Wow'

Nicole Kidman has been left gobsmacked after visiting a giant mural of herself in Sydney.

The 53-year-old Aussie icon uploaded a photo of herself to Instagram, showing her looking shocked with her hand across her mouth as a towering portrait of her stood tall in the background.

“WOW! Thank you Sydney for celebrating #TheUndoing ♥️ It’s back tonight xx” Nicole captioned the photo.

The enormous painting was unveiled on Saturday on the side of an 18-storey high Darlinghurst apartment building.

Eleven artists worked on the portrait - measuring 18.4m by 36.8m - for more than two weeks, battling wind and rain.

The mural shows Nicole with her signature long, wavy auburn curls as she looks into the distance.

The portrait, which is on display until Tuesday, is designed to promote the star’s latest Binge screen series, mystery thriller The Undoing, which she co-produced.

The soaring portrait is a depiction of Kidman as her character, Grace Fraser, a therapist in the psychological thriller. The series also stars Hugh Grant.

To add to the theme of The Undoing twists and turns, the portrait will ‘come undone’ as it unravels into a second artwork from next Tuesday.

The project is temporary and will be painted over and restored back to its original state.

Nicole is currently working on Nine Perfect Strangers in rural Byron Bay, a drama series based on Liane Moriarty’s bestseller of the same name.
