Grinning away as she shared a joke with her co-stars, the mother-of-two looked happy and relaxed as she got to work on set.

Kate accessorized with small red 50s-style sunglasses to protect her eyes from the summer rays, and a long dangling silver necklace.

Maddie, 14, has heaped praise on Kate during their time filming together, saying the pair have become like family members.

Speaking about what she's learned from her co-star, Maddie said: 'I mean everything. She's becoming like a family member to me, so. I love her so much.' 

Although Sia has had a fair amount of experience directing her own music videos, this will be the singer's feature film directorial debut about a sober drug dealer and his autistic sister.

Speaking during a Q&A at Venice Days International Film Fest in 2015, Sia revealed she apprehensive of doing her cinematic project for fear of peer thinking it was simply for 'vanity'.

She said: 'I was too embarrassed to tell anyone I wanted to make a movie because I thought it would be seen as a vanity project because I was a singer.

'And then last year, after I made the Chandelier video, I realized that I was pretty good at directing, so I felt a little bit braver.'  

She added: 'For me, the process was basically, I work out the movie. I’ll act it out, I’ll have the dialogue already in my head. I can’t be bothered to learn Final Draft.

'I’m not a technical person. Like, when I sing, I just want to sing the melody and write the lyrics.'
