Roxy Jacenko reveals daughter Pixie, nine, bathes in $41 anti-ageing Irish seaweed bath every night before bed

Roxy Jacenko's daughter Pixie has inherited her mother's expensive tastes. 

On Tuesday, the PR Queen revealed that the nine-year-old enjoys nightly baths in exotic Irish seaweed. 

In an Instagram Stories post, Roxy showed off the pre-teen's pile of boxes full of the treatment. 

She explained in her caption: 'One kid bathes in magnesium to sleep, the other insists on seaweed of the Irish variety. Good job she can pay her own bills'. 

The treatment, which involves soaking in a tub surrounded by floating tendrils of the sea vegetable, is made by the company Voya. 

It costs $41 for one box, which includes 400g of the seaweed, as well as a portion of sea salt, and is enough for two baths. 

According to the company's website, the 'detoxifying seaweed bath utilises the natural power of wild Irish seaweed to deeply moisturise and purify your skin, and promote rejuvenation.' 

Irish seaweed is believed to be anti-ageing and promotes the 'regeneration and renewal' of the skin. 

Roxy rarely spares an expense when it comes to her children. 

She recently revealed her daughter Pixie's 22-item list of demands for her upcoming tenth birthday.   

Items on the list included a new room, skincare and a glass coffee table, as well as fairy lights, new shoes, and 'trendy clothes'. 

She also wanted crystals, a ring light - which is used to film professional looking videos - and a skin care fridge to store her beauty products. 

Pixie went on to list a teeth whitening kit, lip gloss, makeup, a new swimsuit, a second piercing, and a star light projector.   

The tot already has two successful product lines - Pixie's Bows and Pixie's Fidgets. 

In May, Pixie's line of fidget toys sold a mammoth $200,000 worth in their debut month across Australia.
