But when it comes to food, Roxy Jacenko is all about value, picking up an affordable takeaway meal from Chargrill Charlie's on Thursday.
The 37-year-old wore a head-to-toe designer ensemble as she grabbed lunch with her Sweaty Betty 'clone' Holly Asser.
Roxy, who recently designed a range of healthy salads for the fast food outlet, was seen leaving their Rose Bay store with a bag in hand.
She wore a chic Chanel black dress, which retails for at least $1000, along with a pair of matching $930 ballet flats from the French fashion house.
Concealing her eyes under a pair of $200 Ray Ban aviators, Roxy was draped in expensive jewellery worth over $600,000.
On her right wrist, Roxy wore an Audemars Piguet gold watch, valued at a whopping $75,000.
On her left arm, she wore a $70,000 diamond tennis bracelet from Nader Jewellers and a $9,000 rose gold love bangle from Cartier.
Adorning her wedding finger was her Nicholas Hayward engagement ring worth a reported $450,000.
Topping off her luxury look was a Nicholas Haywood diamond necklace, which retails for $54,000.
Roxy's takeaway lunch trip comes after she spoke to Daily Mail Australia about her day on a plate, revealing she likes to indulge in cheat days.
'I am addicted to killer pythons and chocolate mousse. I don’t eat them often but cant help myself every now and again,' she confessed.
