‘At about 6:00pm Tuesday night we met with a neurosurgeon who broke the heartbreaking news,’ they said. 

‘We are absolutely shattered and the last few days have been our hardest days.’ 

The former Miss Universe Australia, 42, and her partner went on to praise the team at Queensland Children’s Hospital, who are now working with them to determine a treatment plan.

‘Our team at the Queensland Children Hospital have been incredible and remain hopeful that we can remove the mass and get Obi healthy and happy pending the results,’ they added.

The post has since been flooded with messages of support from family, friends and fans, including Erin’s ex-husband Example, who she shares two children with – sons Evander, seven, and Ennio, five.

‘You got this,’ Example wrote, while Steph Claire Smith added: ‘Sending healing love ❤️’.

‘Heartbreaking, he will pull through, kids are tougher than we realise! Sending thoughts and prayers and absolute positive vibes to you all,’ another message read.

The harrowing update follows what was initially a joyful start to parenthood for Erin and Stace, who confirmed the birth of their son exclusively to Daily Mail Australia back in December following his birth in October.

The couple shared at the time that they had named him Obi and were over the moon to bring him home.

‘We are so in love with him, we can’t believe he’s finally here,’ Stace said in December.

‘Fair to say we didn’t get a lot of sleep when we got home from the hospital last night – mostly because we can’t take our eyes off him.’

The former MTV host also previously opened up about her difficult pregnancy, revealing the journey had been ‘a little touch and go at times,’ with health complications in the final trimester.
