Celebrity chef Khanh Ong has revealed the many cosmetic procedures he has had done.

In a candid Q&A on his Instagram Stories, the 30-year-old I'm A Celebrity star was asked 'what treatments/procedures do you get?' as he waited in his cosmetician's chair.

'I get anti-wrinkle around the crow's feet, under my nose and for the first time ever between my eyebrows. I get filler in my jaw (which I love every time I get it done),' he wrote in the caption.

'We have just started doing filler around the outside of my nose towards the bottom of my cheeks because [cosmetic nurse] Alex Pike said it was starting to deflate,' the celebrity foodie added.

Khanh was also asked if there was a procedure that he had done that he didn't like.

The MasterChef Australia star said that while there was nothing he hated, he did get his lips inflated once, but it proved unnecessary.

His nurse talked him out of doing lip fillers again because, 'even at full smile, I still have decent-sized lips,' Khanh said.

In the Q&A session, he was also asked if he had PDO (Polydioxanone) threads done.

A PDO thread lift is a non-surgical procedure, sometimes called a 'lunch time facelift' given the process can be done in around 45 minutes.

It works by injected biodegradable polyester sutures beneath the skin to stimulate collagen production that plumps up sagging skin. 

'I did them around my cheeks and under my neck to get rid of my double chin,' Khanh answered. 

The talented chef was eliminated 5th on the recent season of I'm A Celebrity...Get Me Out of Here.

At the time, his distraught campmates farewelled him as they worried aloud about how they would cope with the cooking after relying on his culinary talents.

In his exit interview, Khanh said that he enjoyed flexing his creative muscles in the camp kitchen.

'Most of the meals were driven by whatever ingredients I got. How I made the most flavour with minimum ingredients or charring things to make more flavour' he said.

'A lot of people helped. Every night I had a sous chef. Everyone was happy for me to do it because it is my happy place.'
