Taking to Instagram, Jules shared a photo of the two Channel Nine reality TV couples spending time together.
'When #MAFS meets these two awesome winners of #9TheBlock!!!' Jules captioned the photo.
'Fantastic achievement! We won love! You won both! Money and you had love!! Amazing,' she wrote
'People who don’t know MAFS always ask me, what do you win?!? Errrhhh LOVE! #bestprize. Can’t wait to catch up again.'
While it’s unclear how the double date came about, both shows are on Nine and Jules went on to describe Hayden and Sara as '#greatpeople', and labelled them '#newfriends'.
Sara, 31, and Hayden, 45, won last year's season of The Block, with their Melbourne apartment netting them a $645,000 profit.
