Roxy Jacenko's 10-year-old son Hunter has been spotted sporting a very pricey backpack.

The 44-year-old PR maven and her son touched down in Australia for three days to visit Roxy's mother Doreen on her birthday.

Taking to Instagram as the family enjoyed a lunch at Icebergs in Bondi, Roxy shared a picture of Hunter wearing a black Louis Vuitton Discovery Backpack.

The bag, with finely embossed Taiga cowhide paired with the brand's signature iconic Monogram canvas, is priced at $4550.

Hunter is no stranger to luxury goods, having developed very expensive tastes like his mother and sister, Pixie, 13.

Jacenko has been accused of spoiling her two children, who she shares with husband Oliver Curtis, with incredibly expensive gifts and lavish birthday parties.

Earlier this year, Hunter shared his 'wish list' ahead of his 11th birthday, with the total cost of the gifts coming to a shocking $12,795.

Posting photos of himself window shopping at several designer stores including Dior and Louis Vuitton, he snapped pictures of the expensive items he wanted his mother to buy him. 

'Birthday wish list shopping has commenced. @roxyjacenko this is simply a GUIDE. More to come,' he wrote in the caption, alongside his shocking reel of images.

Wearing a $1,608 Amiri denim jacket and $2,350 Gucci trackpants during his window shopping outing, Hunter and his mother Roxy made their first stop at the designer store Louis Vuitton.

The most expensive item on his wish list so far is a pair of $4,100 Louis Vuitton boot slippers, which was quickly followed by a $3450 Louis Vuitton wearable wallet.

Next, Hunter took a look at the sunglasses Louis Vuitton had on offer, picking two for his list worth an eye-watering $1,550 and $1,090.

Dior was the next designer store Hunter stopped at, where he picked a pair of sneakers and a white hoody worth $1,400 and $850 respectively. 

Finally, Hunter toned things down a little with a bottle of Replica perfume and Adidas sneakers, which ended up being the cheapest items on his wish list at $215 and $140 respectively. 

Last year, Roxy splashed a rumoured $50,000 on Hunter's extravagant ninth birthday party on a superyacht.

Roxy threw a no-expense-spared Hawaiian-themed party aboard the 122ft charter yacht, Ghost II, which is rented out at $2800 per hour.

The youngsters were treated to custom-made slippers and danced away to a DJ on the cruise around Sydney Harbour.

The three-hour event took a month to plan, and Hunter even got a personalised cake with a topper of himself on a surfboard wearing Hawaiian shorts.

Roxy told The Sunday Telegraph her son chose the theme after looking at albums from a family trip.
