Red hot! Roxy Jacenko, 40, flashes her lacy lingerie in a VERY sultry photo as she moves on from her rapid SAS Australia departure

She infamously quit Channel Seven’s SAS Australia last week, after just six hours.

But PR guru Roxy Jacenko is wasting no time dwelling on her dramatic exit, and instead treated her followers to a very sultry display on Thursday.

Taking to Instagram, the mother of two, 40, shared a sexy photo of herself dressed in red lacy lingerie, as she posed in front of the mirror.

‘Online deliveries,’ she teased in the caption, as she unbuttoned her white Dior dress to reveal just a glimpse of her ample assets in the stunning red underwear.

The red bustier in question is the Marivie set from Honey Birdette, which retails for $280.

It’s been a challenging few weeks for Roxy, who confirmed last Tuesday that she was no longer friends with Candice Warner following a boxing match on SAS Australia.

While Candice happily took several jabs at Roxy during the fight, the Sydney-based publicist claims she refused to retaliate because of their longstanding friendship.

Roxy claimed she reached out to Candice after filming the show in New South Wales’ Snowy Mountains in August and tried to repair their broken friendship.

But instead of accepting the olive branch, Roxy claimed that Candice simply ‘sacked her’ as her manager instead.

However, Candice bit back on Tuesday during an interview on The Morning Show.

She said: ‘Unfortunately there is no talk [between her and Roxy]. It’s a real shame, and it’s really blindsided me.

‘In regards to the fight, I just did what I was instructed to do and if [Roxy] felt uncomfortable with fighting me or anyone, she had an opportunity to pull out before stepping into the ring.

‘I did what I was instructed to do. It’s not just Roxy and I who are friends, we’re friends with everyone on the show and we built relationships with everyone, so regardless of who I was up against it would have been a friend.’

She continued: ‘I think ultimately it’s a shame that it has got to this, because Roxy did a great job. You have to commend anyone who puts their hand up and goes on this show, because it’s hard, it’s brutal, and it’s not for everyone.’
