'It's with a beautiful beautiful man who I can not express how friggen (sic) lucky I am to have in my life. You have no idea how relieved I am to openly and honestly say this out loud!
'Thank you for all that have been on my journey to find love.'
Brooke said she initially met Nick six years ago, but he only noticed her after she starred on The Bachelor last year.
'So happens that I had already met him... 6 years ago... it just took a reality show for him to notice me,' she wrote.
The irony of Nick sharing the same name as Brooke’s last lover, The Bachelor’s Nick Cummins won’t be lost on fans.
Brooke sensationally quit BiP last night, with a distraught Brooke left sobbing after Alex Nation dumped her.
'I feel like a broken little girl right now,' she said before leaving the luxury resort in Fiji and returning to Australia.
Earlier in the episode, Alex dumped Brooke while revealing her decision to focus on her blossoming romance with Bill Goldsmith instead.
'Coming into this I was keen as mustard [on you], and I feel we have really good connection and get each other,' said Alex.
'But I feel like after our date, whilst I still think you're amazing and beautiful, my feelings for Bill have surpassed what was going on with you.'
