Elsa Pataky doesn't look like this anymore! Glamorous actress is unrecognisable as she debuts jaw-dropping new look

Elsa Pataky stunned her fans by debuting a shock new look on social media as she celebrated Halloween on Thursday.

The Spanish-born actress, 48, posted a gallery of photos to Instagram which captured her glaring spookily at the camera as she dressed up as a creepy clown.

The Fast and Furious star's normally flawless visage was covered in pale makeup and bloody red streaks, as a creepy blood-red smile was painted over her mouth.

Her eyes were blacked out with dark mascara and her usually stylish blonde hair was done up in unkempt pigtails.

Elsa completed her creepy look by wearing a shocking yellow and black jumpsuit, as she had fun hamming it up as a creepy clown, in celebration of the spookiest day of the year.

Another photo captured Elsa beaming in the costume as she posed up a storm alongside a female friend.

'Happy Halloween!' Elsa wrote next to the pictures.

The energetic performer lives in a $30million mega-mansion in Byron Bay with her husband Chris Hemsworth and their three children.

Elsa joined a host of Australian celebrities who took to social media to mark Halloween.

Dannii Minogue also opted to ditch her stylish persona, and showcase her edgier side, by using an app to all but erase her famous visage.

The We Could Be the One hitmaker had fans doing a double take as she showed off her ghoulish alter ego with blue skin and red hair.

Dannii's famous lips appeared fuller in the transformation and were highlighted with blood red lipstick, as stitches crisscrossed her face.

The 1984 smash hit Ghostbusters by Ray Parker Jr played in the background, as Dannii worked her angles for her adoring fans, while cartoon skulls danced around the screen.

Dannii and her sister Kylie Minogue are two of Australia's most iconic pop stars, and share similar career trajectories.
