Roxy Jacenko shared a post to social media on Saturday revealing the staggering bill she received after dining at one of Sydney's most exclusive restaurants.

The PR maven, 44, shared a photo of the $1,200 receipt she recently incurred after a round of food and drinks at the Good Luck Restaurant Lounge in Sydney's CBD.

The jaw-dropping meal for Roxy and three friends included 30 jam entrees for $690, kingfish for $44, pickles for $16 and sparkling mineral water for $12.

The blonde bombshell captioned the snap with some hilarious words: 'The ratio of margaritas to humans.'

Roxy also posted some photos of the mouth-watering Chinese meal she enjoyed with friends, which included freshly prepared lobster, dim sims, dumplings and spring rolls.

The lavish night out looked to be a welcome distraction for Roxy, who is dealing with the aftermath of her failed business venture, in which people paid for the chance to win a luxurious $10million house.  

Earlier this year, Roxy documented her weight loss journey over the past year, amid her lavish lifestyle and relocation to Singapore. 

In April, Jacenko revealed she had reached her goal weight after shedding 15 kilograms.

Roxy took to Instagram to share the good news and to reveal what she would be doing to celebrate. 

In one post, the former Sweaty Betty owner showed a picture of her scales revealing her current weight of 51.9kg.

A subsequent update showed a picture of a bag of Krispy Kreme doughnuts, along with a claim she would be eating them as a treat for reaching her goal.

Prior to that, Roxy unveiled her astonishing weight loss to social media, along with details of the strict diet she used to shrink her frame.

The mother-of-two, who is now based in Singapore, shared a photo of herself looking very svelte in black shorts and a sports bra while working out at the gym. 

'12kg down - shall I do a day on a plate and my gym schedule?' she wrote in a poll next to the mirror selfie. 

Roxy also gave her fans an update on her alcohol consumption, revealing she had finally ditched the booze altogether.
