The pair had only been back in Australia for less than 24 hours, after jetting back from Fiji, where the show is filmed.
Body language expert Louise Mahler says Alex and Bill’s steamy kissing session was more revealing than they’d perhaps intended.
“Here is a woman hanging off a man, contorting her body off the seat, crossing her body with her arm,” the expert said.
“The kissing photos are clearly photos of lust with wide mouths and what appear to be deep tongues. This is meaningless lust and gives no indication of a ‘relationship’ beyond the bedroom.
“The self-conscious fiddling with the clothes, the unstable body, the hair across the face, the vocal fry and the uncertain eye contact are just disturbing.
“Clearly this is from the school of Kardashian,” the expert concluded.
Alex has quite the history with public relationships. She fell in love with Bachelor Richie, but they then split after a year – and in a teaser for the new show, she describes the ending as a 'grubby' split.
She then went public with her relationship with Maegan Luxa - her teammate in a Melbourne women's AFL team the Frankston Bombers.
‘When it comes to love, my friends and family would tell you that my heart isn’t one to discriminate,” Alex wrote on Instagram at the time.
That relationship ended too – and now only time will tell of the TV show that brought her so much unhappiness the first time will end differently now.
