Roxy Jacenko is enjoying her updated bust and she is happy to show it off. 

The 44-year-old stepped out in Double Bay on Thursday to grab a green juice and was looking fit and fabulous. 

The PR Queen opted for a skintight activewear set from P.E Nation, including a black and white crop top that showcased her cleavage. 

She added a pair of tights and a cap, while wearing a silver choker for a touch of luxury in her sporty ensemble. 

Roxy finished her ensemble with sneakers and a natural makeup look, while tucking her blonde locks under her cap. 

She carried her smart phone in her hand and strode along at speed, being the busy professional she is.  

The star underwent breast revision surgery earlier this month after discovering one of her implants had ruptured. 

The procedure was handled by 'boob' specialist Dr Anoop Rastogi on Thursday and the PR Queen was spotted out and about in Double Bay just two days later.

Daily Mail Australia believes Roxy went up a size from her previous implants and she looked quite ample in her low-cut frock.

She returned back to work at her Talent and PR agency, The Ministry of Talent, this week.

Prior to her surgery, Roxy told Daily Mail Australia that while the rupture occurred in one implant only, she would be having both removed and replaced.

'I'll be having the implants removed in two weeks, and replaced at the same time,' she said last month.

The rupture was discovered during a routine MRI that is part of her annual cancer check-up. She hadn't been in for one in two years.

She said that while she suffered some initial shock at the news, an implant rupture wasn't entirely unexpected.

'I was somewhat shocked when I received the update, but I guess it's par for the course when you put something in which really isn’t meant to be there,' Roxy said. 

'During radiation, when I was being treated for breast cancer, I had capsular contractor on the same side, so revision surgery is not something I haven’t had to do before.'

Despite the current health scare, Roxy said that she has not considered removing her implants altogether.

'Not at all, I have had them since I was 24,' she said.

'If anything, what it reminds me is not to be so ignorant about doing annual check-ups regarding my previous cancer diagnosis.'

She even had advice for women who were considering implants for themselves.

'If you aren’t happy with what God gave you, change it,' she said.

'I am all about doing what is right for you, and not worrying about what other people think. I am not the first with a rupture and wont be the last.'

Roxy was diagnosed with breast cancer in 2016 at the age of 36, and endured a six-week radiation program before receiving partial removal surgery.
