Married At First Sight star Tim Calwell goes Instagram official with his Brazilian bombshell girlfriend Barbara after split with TV bride Sara Mesa

Married At First Sight’s Tim Calwell has finally gone Instagram official with his Brazilian bombshell girlfriend Barbara after his split with his TV bride Sara Mesa.

The 32-year-old Gold Coast business owner couldn’t wipe the smile off his face as he posed for a series of loved-up photos with his glamorous partner.

While Tim is yet to share photos on his own Instagram page, which is still in control of Channel Nine, Daily Mail Australia can reveal Barbara has been flaunting their romance on her private account.

Earlier this month, the brunette beauty shared a sweet tribute to Tim for his 32nd birthday.

‘Bday boy Appreciation post for this handsome man who makes me happy every day!’ she captioned the post. 

Tim and Barbara met in February, just weeks after his ill-fated marriage with Sydney-based nutritionist Sara went to air.

Not long after, the pair were spotted buying some takeaway food and drinks before heading to a nursery to buy some plants.

Speaking to Daily Mail Australia, Tim adamantly denied cheating on his TV bride and insisted he only began to pursue his relationship with Barbara after splitting with Sara. 

‘No I wasn’t seeing anyone through the experiment. I was literally locked in, dialled in, trying to make our relationship work,’ he explained at the time. 

‘I don’t know why, if she’s bringing that up… she’s trying to throw heat on my end to try and distract, maybe, from whatever going on in her ballpark.’

Tim described his TV marriage with Sara as ‘toxic’ and very up and down.

‘It was definitely very up and down. Almost toxic at this point, I don’t know,’ he said.

‘We were trying our best to be in a relationship. The whole experience is very intense anyway… it was definitely wasn’t comfortable for me.’

He also referred to a dinner party blow-up where he claimed Sara had cancelled dates with him on three occasions and she responded furiously.

‘I think her bailing on the dates was more of a catalyst for the other things that were going on behind the scenes,’ he said.

‘I was getting really frustrated by being spoken over and talked down to.

‘My feelings and my opinions were just being thrown back in my face and it just felt like nothing I had to say was valid.’

Tim admitted his frustration may not have entirely come from the cancelled dates.

‘It’s more of a catalyst of my frustrations of being put down over the course of the three weeks or however long it was,’ he said.
