Roxy Jacenko flaunted her very toned frame on Thursday aa she hit the gym for a workout session.

The socialite, 44, took to Instagram to share two images of her enviable post-workout form. 

One photo showed Roxy standing in front of a full-length mirror, her face obscured by her phone.

The mum-of two flaunted her slender pins in a pair of figure-hugging black leggings and a pair of white sneakers.

Her gym ensemble was finished with a black scoop neck sports bra with thin straps that showed off her washboard abs to full effect.

The garment also placed her well-maintained arms well and truly in the spotlight. 

Roxy shared a second image to the social media platform from the same workkout session.

This time, Roxy had replaced the leggings with some black shorts and while her face was again obscured by the phone, here lithe form was on full display.

'Fills the days,' she simply captioned the image.   

Insiders on The Block recently revealed a big Sydney star almost walked away with the keys to House Two from the 2023 season after placing a big-money bid on it.

Daily Mail Australia revealed Roxy was said to have been in talks with executive producer and co-creator Julian Cress about a property on Charming Street in Melbourne's Hampton East.

The socialite, 44, had her eyes on the renovation done by Queensland couple Leah and Ash Milton after their house was passed in at auction. 

'Those phone calls started months after the show wrapped. With even the 2023 contestants unaware that those conversations were happening,' one source said.

While Roxy did not confirm why she wanted to purchase the property, some speculated she had plans to follow in the footsteps of Adrian 'Mr Lambo' Portelli.

Adrian, 34, who is now one of Australia's youngest billionaires, shot to fame on The Block in 2022 when he got into a bidding war with Block veteran Danny Wallis.

Since then, the LMCT+ founder bought three houses from the 2023 season and has used them as prizes in ticketed giveaways sold through his business.

At the time Roxy considered purchasing House Two, she was launching her online marketing course Roxy's Bootcamp, which debuted with a mansion giveaway.

'It is unconfirmed if Roxy did intend to follow Adrian Portelli and auction off the property but it seemed likely that was where the sale was going,' one source said.

'An offer is an offer and they [The Block producers] don't ask those questions.'

Leah and Ash went on to sell their property in Hampton East to a private buyer for $3,125,000, netting them a profit of $155,000.

While Roxy did not purchase a Block house last year, an insider revealed the PR queen is more than welcome to take another crack at the auction in October.  

'[Celebrity] involvement ads to show excitement and these heavy hitters have been a huge part in the way the last few seasons have played out,' they said.

'This year's location is very appealing to all buyers looking for a holiday escape and these properties won't be just appealing to Melbournians.'
