MAFS star Martha Kalifatidis and mother Mary arrive in Adelaide for getaway

They are becoming one of Australia’s most famous reality TV families. 

And Married At First Sight star Martha Kalifatidis, 32, looked every inch the off-duty star as she arrived in Adelaide with her Big Brother housemate mother Mary and lookalike sister Sophie on Saturday. 

The trio were spotted making their way through airport after flying into the South Australian capital for an interstate girls trip.

Martha cut a stylish figure wearing a body-hugging black dress, which featured a plunging neckline and cut-outs around the waist. 

The raven-haired star paired the dress with a pair of black designer boots and a thick, silver necklace. 

At times, she covered her nose and mouth with a blue surgical face mask.

The family are now enjoying a new round of fame since Mary appeared on the latest season of Big Brother.  

On Wednesday, Martha decided to troll her mother relentlessly after she ‘got glam’ to do the housework amid her new-found reality TV fame.

‘You’re so glam now you’re on Big Brother!’ Martha quipped to her mother in an Instagram video. ‘Do you wear makeup to vacuum? Oh my God, now that you’re a celeb!’

Martha then ran up to Mary, who furiously pointed the vacuum tube at her daughter in rage.  

‘F**k off, Martha!’ Mary bit back.

Indeed, Mary has caused quite the stir on Big Brother this season – only recently playing a hilarious prank on her housemates.

Mary snuck in several hats with rude Greek sayings, and tricked a handful of her housemates into wearing them on television.  

On Monday, Nicholas Benton was made aware of the prank and addressed his embarrassing predicament on Instagram.

‘Hey Nick, I have a cool hat for you to wear. It means “legend” in Greek,’ he captioned a photo of Mary looking mischievous on the show.

He then shared a gallery of photos of himself wearing the Savvas Says ‘Malaka!’ hats in the Big Brother house, and revealed what the word actually meant.   

Malaka means ‘a man who masturbates’ in Greek, and is typically used as an insult similar to the English word ‘w**ker’. 

Mary and Sarah Jane ‘SJ’ Adams were involved in a double elimination on Tuesday – but all was not as it seemed.

Big Brother whisked them away to a secret attic where they remained safe from eviction as part of ‘Surprise Week’.

The pair returned to the competition by jumping out of a large cake on Wednesday night’s episode, shocking their housemates in the process.

Big Brother Australia continues on Sunday from 7pm on Channel Seven
