Brooks Shocking Secrets Exposed Amid Pregnancy Leaks!

The new season of Married At First Sight is off to a sensational start, rocked by a string of scandals - several of them .

After news broke last week that the 27-year-old part-time model had reconnected with her ex while still part of the experiment - and that she was now pregnant with his child - the Mail can reveal another explosive secret.

In photos obtained by Daily Mail, Brook was seen sporting what looked to be an engagement ring, confirming a rumour about her that had been swirling for weeks.

Despite recently denying she was hiding any 'big news', Brook let the cat out of the bag while on a solo walk on the  last Tuesday. 

Going makeup free, she cut a casual figure in a loose-fitting jumper, black and white shorts and lilac Crocs. She seemingly tried to keep the ring away from prying eyes, using the sleeve of her jumper to cover her hand.

But Brook's ruse was exposed when she took a phone call, accidentally exposing the ring in full view of our photographer.

Right as this story was published, news broke that Brook had sold the story of her pregnancy and engagement exclusively to a tabloid magazine. 

'It was a total betrayal of the experiment and everyone is filthy about it,' said an insider. 

'One of the lowest acts in the history of the show.'

It comes after we revealed Brook was the bride accused of secretly rekindling things with a former flame while still filming the show - and that man is the father of her unborn child.

In footage obtained by the Mail, Brook was seen kissing her ex-boyfriend Harry as the pair decorated a Christmas tree together last October.

It was unusually early for festive celebrations - but the more significant detail was that just weeks earlier, her on-screen marriage to Chris Nield had fallen apart while they were filming the show in Sydney.

The intimate video showed Brook and Harry embracing inside an apartment.

For the cast and crew, the reveal was less a shock, and more confirmation of what many had already suspected: Brook hadn't cut ties with her ex and Chris never stood a chance.
