MAFS’ Martha Kalifatidis looks stressed out while filming Celebrity Apprentice

Martha Kalifatidis is currently filming the new season of Celebrity Apprentice.

And as the production heads into its seventh week, the 31-year-old is starting to look well and truly over it.

The Married At First Sight star looked rather unimpressed while shooting scenes at Sydney’s Carriageworks on Tuesday.

She appeared to be annoyed as she stepped outside for a breather.

Martha raised her arms up to her head to block out the sun, and appeared to be keeping her distance from the crew.

She was dressed in baggy jeans and an oversized tie-dye shirt, which was tucked in at the front.

Martha styled her hair loosely, and opted for minimal makeup for the occasion.

She completed her look with hoop earrings and a pair of white sneakers.

Meanwhile, fellow contestant Shaynna Blaze seemed to be enjoying the process a lot more. 

The Block star, 57, beamed with joy nearby as she stepped out for some sunshine. 

She was smiling ear to ear and looking about her surroundings during a quick break from filming a challenge.

The mother of two wore high-waisted red pants, a low-cut navy singlet and a pair of blue rubber gloves.

She completed her look with large earrings and Gucci shoes.

Other stars taking part in the reality show include Lisa and Jess Origliasso from The Veronicas, The Biggest Loser’s Michelle Bridges and kaftan designer Camilla Franks.
