The brother and sister duo stepped out in Los Angeles yesterday (18 November) for the premiere of The Hunger Games: Catching Fire and managed to turn heads in more ways than one.
15-year-old Jaden immediately made an impact by arriving at the screening in odd trainers - a combination that he has been seen wearing at other A-list events.
He also wore a pair of black jeans and a kimono style top. Perhaps he was paying homage to The Karate Kid remake, which he starred in alongside Jackie Chan in 2010.
Meanwhile, his younger sister Willow sported a similar Japanese-influenced top in a light blue colour.
She also donned a pair of shiny black leggings, some chunky boots and edgy black nail varnish.
The pop songstress has been experimenting with numerous wacky hairstyles over the past year, but last night she stuck to her latest (and less striking) straight black 'do.
As if Jaden and Willow's ensembles weren't worthy enough of photos, the pair then decided to pull a variety of comical poses on the red carpet before heading into the cinema to watch the film.
In one snap they can be seen closing their eyes and with their hands in a prayer position, whereas another pictures shows Jaden stood in a Karate stance.
It's clear that they've both inherited their dad Will Smith's cheeky sense of humour!
The siblings also proved how close they are by holding hands with one another on arrival and Jaden was spotted putting a protective arm around Willow at one point too.
