Michelle posed alongside her I'm A Celebrity co-star, Khanh Ong, who looked chic in a brown suit. 

The MasterChef Australia star wore the jacket over his shoulders while donning a black top and added leather boots. 

He finished the look with a designer watch and a number of dangling cross earrings in silver. 

Also turning heads was Married At First Sight star Selina Chhaur who kept things bright in white. 

The former reality personality wore a sleeveless cream mini dress with dramatic feathered details across the bust. 

She carried a glittering purse that dripped with gems and matched her strappy heels. 

The beauty opted for a peachy makeup look with a soft pink lipstick while wearing her hair piled high in a retro do.
